2011- Service Trailer Brake System

B0100 code, 2011, Silverado, 1500 4 x 4, 5.3L, Flex Fuel.
DIC shows message "Service Trailer Brake System".
A scan for codes shows seven events.
1. Short in D Squib Circuit. What and Where is D Squib? One of the Electronic Modules in the brake system some where?
2. FSC DTC What is FSC? Maybe...Front Sensor? Where?
3. MIL
4. History
5-7 repeats above.
These codes were manufacture specific to Chevy. No other codes.
No trailer is hooked up. Seems to show most frequently while backing out of the garage in cold weather. I can clear the code but it immediately registers again.
I noticed today that my battery seems to have a slow drain also. This was after 3 days of not driving it. Related...?


1996 chevy 5.7 miss fire only when it's cold

Ok i have a 1996 chevy silverado 5.7 vortec 4x4 ok.....so, when i start it, it runs fine for about 2 to 3 minutes then it starts to miss and back fire for about 15 to 20 min. and the check engine light comes on. I park, come back about 10 min later to leave and it does not want to start. After it does start it still misses and then it all stops after running it for about another 30~40 min. and the light goes off and runs fine


Re: transmission only has 1st and second gear

I would verify your fluid level and the color and smell of your transmission fluid. But it sounds like the trans is worn. Cold, when the fluid is thicker will let it catch for a while but when the fluid warms and thins it will just slip.

you should talk to a trans specialist


2003 Chevy grinding noise

I have a 2003 chevy silverado z71, my check engine light came on and now I hear a grinding noise when the truck is in gear. It has this noise going forward and in reverse (all the time moving slow or fast), however if I shift it to neutral while rolling the noise stops. Is this the tranny or the transfer case?


1994 c1500 ignition coil plug wire keeps burning out

I have a 1994 chevy 1500 with a 350 motor in it. It died the other day at a red light the engine died I put it in neutral, and re started it. It ran two minutes then died again. I was getting no spark and the rotor an distributor cap were fouled with corrosion so I replaced them. Still had no spark so and none coming from the ignition coil so I replaced that as well. Then my brain kicked in and I tested the plug wires, turns out the wire between the cap and coil was dead. The truck fired right up and ran for twenty minutes the died. I checked the brand bed wires and the one between the coil and cap is dead. I got a new set of plug wires thinking maybe it was a Defective set, ( have to love auto zone's lifetime warranty )
Put the new wire on and it would not crank at all checked the wire an it's has no connectivity using the ohms meter.
Is there a chance someone knows where my problem is?

temp problems

I have a 94 chevy pick up with a 5.7l and a 350hp. Shat would cause my temp to go to max when my truck is turned off?


Re: possible short? Please help

you should have a volt gauge not an amp gauge. having the gauge move when the blinkers are flashing is normal unless it is going to far to the discharge side.

you should use a dvom and check to see if the battery voltage is 13.8 to 14.2 with the engine running.

first things to check, I would verify that the alternator is charging correctly and check to see if there is a draw on the battery when the engine is not running.


1991 Chevy Cheyenne sudden knocking in engine

I parked my truck last night and all was good with the world. Got in it just now and tri to start it, it turned over then clicked. I checked the battery cables...loose, so I tightened. The truck then started and is now knocking in the drivers side. Checked oil, its fine. What could cause this sudden knocking? Possibly the oil pump?


Truck cuts on and off while driving

Hey guys- my 2010 silverado cuts on and off while I'm driving- it's like a complete shut off but my truck keeps going and doesn't stop- it jerks real hard. My friend put a computer on my car and no codes are coming up? Anyone know of this problem happening in other trucks or possibly have a solution?

Thanks.

94 z71 Brake light/acceleration issues

Guys I need some help.
I bought a 1994 z71 350 automatic. When the truck sits for a while the parking brake light comes on within the first minute or two of driving. Soon after the light comes on I start having a slight loss in acceration at low rpm. When it gets close to shifting, at higher rpm, I have a complete loss of acceration, almost like it shifts into neutral because it revs up. If I let off the gas it shifts and then the cycle repeats. Then my speedometer starts jumping around. Sometimes my service engine light comes on with it but sometimes it doesn't. The only other problem I have is that the brakes are pretty spongy and the temp gauge hardly budges (I am no expert so I don't know if a faulty temp sensor or such could be related). After it does this and then sits for a while it doesn't do it again. As long as I drive it at least every other day it will not do this. But more than that you can bet that light will come on. When I bought it I replaced the front pads, rotors, cv shafts, fuel filter, oil and filter, air filter, plugs, tps, and knock sensor. I also had a trans shop replace all the trans seals and gaskets plus filter. I'm out of ideas. Thanks in advance for the advice.


airbag

I just got chev 2008 silverado 1500 and airbag light is on but has not been deployed, it was in accident in rear bumper will I have to get new censor or can I get it reset or could it be something else?


Re: need a pro…………2001 silver ado p0121

you're going to need to look at the freeze frame data for your code. once you see where it is acting up, you will need to drive with a scanner hooked up and graphing your dtat stream. See it there is a glitch in your TPS circuit. Make sure to watch toy TPS voltage when you let off the throttle. See if you can notice if the TPS voltage stays too high. Should drop below 1.0 volt when you let off the gas pedal. If there are any drop outs check you wiring to the TPS.


98' C2500 will not Crank

I am at the Hair pulling stage and I don't have much left! Please help!

I have a no crank situation with my 98' chevy 2500 5.7 vortec. It started right up yesterday; I drove to bank ran in and out, truck would not start. 30 minutes later it started. I then drove home, ran in grabbed something and it would not start again. 30 minutes later it started. I drove to store it would not restart, towed it home to my shop where it sits now. I have gone through all the usual steps of testing everything from the key up to the starter. Here is what I have so far:

1) Remote switch to starter and it cranks. Bench test starter not necessary at this point I believe.
2) multi meter to S post on starter, key to ignition position, meter shows 11.2 volts at S post, key off meter shows 0 volts.
3) swapped out starter relay with brand new one, no changes. Tested both sides of relay block(constant and key on) 12.9 volts.
4) Security system light does go out after 5 seconds, so that is not issue, I think?
5) adjusted neutral safety switch every which way, no change. tried to start in neutral, no change.

It would appear that from the key to the starter all the power is where it should be!???? What am I missing???

Many Thanks In Advance!!!!!!

2004 chevy silverado gauges not working

I have a 2000 chevy silverado and i did an engine swap from a 4.3L motor to a 5.3L. But the engine i installed its from a chevy 2004 and bu the time i was finished with my truck, i noticed that the gauges weren't working. I turned my truck on and none of the gauges weren't working not even the RPM. So i connected my computer scanner to see wat it was and as soon i plug my scanner on the PED connection, the gauges started working and i disconnect the scanner and it stopped working. I already cheked all the ground wires and i doubled check if i had missed a harness connection but everything was connected fine.. I already have like 3 weeks and i cant find a solution to fix the gauges.

Chevy Silverado ac belt knocking

I have an 03 silverado 5.3l v8. Ac problems. Last year, my compressor (I'm assuming) would cause my ac tensioner to knock and broke 2 belts. Assuming bad compressor, I left the belt of and dealt with the heat. This year, I tried again and put a new belt on. Knocking was gone. Freon was low and I unscrewed high side valve and it flew off. Realized I had a leak at the high side valve. I then changed the valve, orifice, and accumulator. Evacuated system with pump. System helda vacuum. Refilled freon (only one can put it in the green which according to autozone is way less than what the system should hold). Blew cold at idle. As soon as I drove off, it stopped blowing cold, only slightly cool. Clutch stays on as it should. The old orifice looked like it had metal dust on it. Could it be sensor or compressor? I have the dual manual climate controls inside. Also, my truck seems to be getting low on coolant lately. Not sure if that could be related. I don't have check engine light. Please help

Air not coming out of vents

I have a 1999 Silverado 1500 .When you turn on the blower for the AC or the heater you can hear the blower running but no air comes out of the vents. Is there a relay or sensor that could be bad? Air does come out of the top vents when defrost is on. Air comes out of bottom vent also. 10 amp fuse for ac/heater is good.


Ripped Off by a Dealership??????

A friend took his 1996 Chevy 2500 to a dealership to have the front drivers side axle seal replaced In doing so the dealership managed to ruin axle and the adjusting nut for ring gear. He said that he used a slide hammer which i dont believe, then he cut the mounting plate off the axle, and then Mutilated the nut with a punch and hammer. Which cost him and extra 600 dollars. I think He ruined the nut with the torch. then he tried to explain that he put a puller on the axle which makes absolutely no scents what are you going to pull off of? he said that the plate was cracked I can guess how that happened, Any thoughts? Thanks


2001 Silverado 4.8 V8, High Pitch Air Release from AC?

I'm getting a high pitch air pressure release noise like an , "Air Brake" from someplace in the front of the engine. It happens when the AC is engaged, defrost also. It doesn't do it when AC is off. Noise happens in an instant at rev RPM in park or during acceleration on the road. The AC pressures are all on specs and there have never been any problems with the compressor or system parts in the past. The compressor clutch cycles as it should. All lines are cold and hot as they should be to the touch during cycle. This started midway through last summer. The AC blows cold 40 degree air on the hottest most humid days. This noise is loud enough it turns heads when I'm passing people on the street. Hope somebody can help me out soon. :? :x :roll:


2012 Canyon 3700 Vortec

What would cause less fuel mileage? I have a 2012 Canyon with the 3700 Vortec engine. I have noticed that I used to get very good mileage and now it seems that it has gone way down. No engine light has come on, the smell of gas comes in the cab when first started. I have sent it to the dealer and they say that there is nothing wrong with the mileage but I know different. They think the mileage is normal. They can't read with the computer because no light has come on. I used to be able to go up to the cottage and about a quarter of the way back on a tank. The cottage is about 515km (roughly 300m) and the tank is about 66L (roughly 20gal), so about 640kms (roughly 375m) I used to get. Now I only get about about 380kms (roughly 220m) on a tank. Does anyone know what could be causing this? Also what should my rpm's be at when running on the highway anywhere from 100 - 120kms (60 - 80ms)?

94 chevy k1500 running issues

got a mechanical question for you, got a 94 chevy k1500 with a 5.7 v8 with throttle body injection, boggs down at stops and when accelerating basically anytime there is a load on the engine, fine when in park or neutral, replaced spark plugs, wires, coil, air and fuel filter, oil change, and idle air control valve. still does it not as bad but still does it, there is no cat to get clogged but the muffler does have a hole in it


08 Silverado V8 4.8L

I just had some warranty work done on my truck. I had to change the throttle body sensor and the evap sensor. As I was pulling out of the dealer the engine light came on again, turned around and got them to check the code. The mechanic showed me the computer and it said that piston 8 is misfiring. He suggested changing the plugs first and see if that fixes the problem. He also said that if that doesn't work than change the wires, if that doesn't work than the problem is deaper. Do I trust this guy and start with plugs or could it be something else wrong? Also what would be the side effects of letting this go too long?

1993 silverado rear lights

Bad Driver's Door Module???

For the past few weeks, when the temperatures have been in the single digits, my key fob would not actuate the door lock on the driver's door. Once temps warmed up a bit,
it worked. This past Friday as I was driving to work, nothing at the module worked; locks, windows, mirror, etc., and hasn't since.

I pulled the module and attempted to test for power. I am getting battery voltage at the 4-wire connector toward the front of the module, at the orange wire (#2) and have
continuity between ground and the black wire (#4).

Image

Because of the size of the wires, I have to assume this is the connector I should be checking, prior to replacing the module. Am I correct?

Any help is deeply appreciated.

94 Chevy 1500 leaking and won't stay cranked

My 94 Chevy is leaking oil in it looks like 4 different places. I have oil under my truck and behind the passenger front tire. Its been idleing bad and when I am stopped and start to push the gas it jerks when it takes off a few times. It has a hard time gassing up hills and acts like it doesn't want to go at first when I press the gas pedal. If i push the break or let off the gas for a little bit, it automatically dies. And takes about two to three times to get it back cranked and I immediately have to press the gas to keep it running. There is also a rattling noise under the hood when I am pressing the gas but immediately stops when I take my foot off the pedal. Can anyone tell me what the problem may be?

engine/tranny moved back, now no reverse and tranny noise

Hi folks brand new here. I've got a weird situation with my buddies 02 silverado 2wd. It seems his engine/tranny slid back(?) against his fire wall. It looks fine under the hood to me as far as position except the passenger side rear spark plug wire is definitely touching fire wall. Then again, I'm not real familiar with this truck so I have no point of reference. He was getting on the freeway at about 35mph when he heard a thud and pulled over. He was able to limp it along home but tranny makes noise at above 25 - 30 mph. as well he now has no reverse. I looked under the rear cross member where the tranny mount is bolted to xmember and the washer seems to have moved back about 3/8". I jacked up the truck and then put a jack (carefully) under the engine to see if the rubber on the front mounts had seperated and had caused the engine/tranny to move but both sides seemed ok. The driver side did look separate but when jacking under engine, the whole front end lifted, telling me that the rubber hadn't separated. Also, the u joint had a dab tranny fluid on it. So, uhhhhhh? Anyone?


Idle troubles, check engine light and cranks but wont start

I have a 2004 Chevrolet Silverado I bought at the end of September and if has been running great, til last night. I got in it to head to work, I started it up, and the idle was REALLY rough, I turned off the motor, gave it a moment and started it up again. This time the idle was really fairly smooth, but the check engine light was on, not flashing, just on steady. The idle was only at between 500 and 600 rpm. I got to work, did my shift and this morning when I started it up, it was just slightly rough and the idle was fine at about 750 rpm. I got home, parked, turned it off, came up to my computer in the apartment, did some searching on the subject and saw something about some part places having the scanners to diagnose possible troubles. I went back out to the truck, inserted the key, and she cranked away, but wont start. she's got 3/4 tank of gas. Any idea's? Similar experiences???


97 Silverado after misstart will not start at all

My 97 will not start if after trying to start I let the key return before it starts, once doing so all it will do is just crank and crank with no sign of starting. The check engine light will come on. Disconnecting the battery for several days (4) it started once connected again, the time before it was close to a month. Thanks for any help

1999 Chevy Silverado Radio noise

I'm having trouble with interference on AM stations only. Suggestions? Solutions?


Re: 2003 Silverado Instrument Cluster lights and gauges

you're going to need to scan your instrument cluster. there have been instances where the wire harness out in the hood area rubs through. Also there are times where the soldered pin on the circuit board breaks loose. But by scanning the cluster you can see what the reading are doing.


chevy 1991 c1500 doesn't want to idle when warm

I have a 1991 chevy c 1500 with a 305 engine it will start and idle great when cold as it warms up it will stall if i disconnect the water sensor it goes back to high idle like its cold i changed the sensor but it still does the same thing what else can i try


Re: 90 chevy silverado dies when i floor it

high idle could be from a couple of things, coolant temp sensor reading too cold or it could be a vacuum leak. there may be other things but I would look at those two first. Either one could also affect smog inspection. Why didn't you say what your truck was failed for? High hydrocarbons? High CO? of what does your state look at for to pass?

Fuel pressure and volume could be a possibility. Hows the O2 sensor trims? LT (long term) and ST (short term) fuel trims will tell you how the exhaust gases are being interpreted by your computer and in effect how your computer feeds your engine.

If your service engine light came on you should have your truck scanned to see what the code or codes are and go from there.


93 Chevy PU keeps getting a check engine light for faulty O2

I have a 93 chevy C1500 with TBI. While driving check engine light comes on. Until the code is erased, idle engine speed fluctuates and eventually shuts off. The code says bad O2 sensor. Don't believe this is the problem since I've replaced it twice. Also, the fuel pump has been replaced twice, plugs, wires, distributor cap rotter and coil, EGR valve, MAP sensor, TP Sensor, cleaned off all engine grounds and none of that fixed the problem. Any other suggestions?


Re: Silverado instrument cluster panel lighting

does it go bright and dim with the engine rpm? Or when you are driving at a steady speed it does it? Does it still do it if the lights are on and the engine is not running? Trying to see if it tied to the alternator output or if there is a draw in the circuit.

A year of the truck would determine what kind of instrument cluster and lights you have.


Cluster gauge Chevy 1500 problem

My 95 1500 Chevy is having problem. The air bag light comes on when I accelerate, the battery gauge on the instrumen cluster maxes out, the interior and exterio lights get brighter when I accelerate. Also, their is a wining noise that comes from the alternato when I press on the accelerato. Does anyone have a clue of what this could be?

Re: 99 running rough until i hit 2000 rpms

any codes stored in memory? Freeze frame? have you looked for misfires with a scanner? What are your fuel trims? how's your fuel pressure regulator? check it for a leak to vacuum?

96 z71 trans problem

I have a 96 z71 it ran good until it was envoled in a wreck on driver side now just test drove it first time after i fixed it and the trans is acting up shifts in to 1/2 but 2/3 shifts hard and it shifted into overdrive once but it went right back out. Now it wont shift into overdrive had to do some heavy fixing replaced the driver finder, hood, grill, headlights, interfinder well, radiator, clutch fan, and radiator support and driver door. What is worng with my truck?


Re: '89 Silverado power loss

this is a tough one. Intermittent power loss could be a bunch of different things. electrical, mechanical, fuel pressure... you will need to have the problem happen while you have a scanner or an electrical circuit tester box attached to see what happens when the problem occurs.


Re: 2004 Chevy Silverado

check for codes to see what the computers are looking for. Ecm, Bcm, Abs.


99 silverado z71, driver side rear wheel is locked up

98 Chevy 2500 Z71 Lost All Gears

hey guys, i have a 98 2500 Z71 that is having some issues. it started a few months ago when i was helping a buddy move. at first the tranny would shift outta od all on its own. this lasted a couple months. then while i was headed home with my buddies stuff i lost all gears. the sound that came from the drivetrain was a sound like it got put in park while the truck was still moving. like i said i lost all gears and it has got me puzzled. any ideas thoughts or comments would be great. my tranny is 4L80E with a np 241c t-case.


Re: 2002 Chevy avalanche 5.3 Stalls when you turn steering w

Re: 2000 chevy 3500 5.7 won't crank

Put a socket and ratchet on the crank bolt in the center of the harmonic balancer and turn the engine over. NOT TO START THE ENGINE but to see if the engine is froze up. If the motor won't turn over remove all the spark plugs and then try it again. Check to see if you have a hydrostatic lock in a cylinder. Be careful. May be coolant, may be fuel. If you have a cylinder full of a liquid it will be pushed out the spark plug hole and let you turn the engine. if the engine still doesn't turn with all the spark plugs out you may want to call your supplier.

How did you know you had an air pocket in the cooling system?


Re: 2000 chevy silverado engine knock trans stuck

have you talked with the repair place that did your heads? Did you have a shop work on it or just some mechanic? If you have a problem with a lifter or a rocker arm that may be ca contributing factor to and engine miss. Any engine miss will affect your oxygen sensor readings. If your SES (service engine soon) light comes on it may put your vehicle in limp mode and make your transmission stay in second gear. Your gauges not working may also put you into limp mode. Some things may be related but it's also possible that you have a separate problem for each defect. Talk to the shop about the engine noise. Scan for all the codes that are stored and start from there.


Why does my parking break light keep coming on while driving

So I just changed my rear drum brakes myself for the first time. Anyways at first I noticed a grinding noise. After I took the tire off to check what it was one of the springs came off holding the metal aduster. Anyway I put the tire back on and now its making another noise from the same side Im not sure if it has anything to do with the light being on.

What I can tell you about the parking light being on is it comes on when I start driving and when I come to a complete stop it goes off. Sometimes it stays off for awhile.

Also I my dad helped me change the front disc brakes 2 months ago they are fine. I got a brake inspection done on my truck the abs light was on and 2 abs sensors need to be replaced as well as the master cylinder. I just barely finished replacing the master cylinder. I dont think any of these things has anything to do with the parking light being on though.


Chevy Silverado ac light

I have a 1993 chevy silveroldo their is a warning light on the dash for the ac .


Re: 2006 silverado will not go in drive

Sounds like something broke inside the transmission. A pop sound is never good. There is nothing like a simple shift solenoid that can cause the problem you are having. There is an internal problem inside the transmission.


Re: a/c stays cool

If all the components are new and functional, it really could only be a couple different things. First off, and most common would be an incorrect amount of refrigerant in the a/c system. You should really double check that with an air conditioning recovery/recharge machine. Trusting the amount in a can of refrigerant or a quick charge kit is very unreliable.

Another possibility is a partially clogged evaporator core. If you've had any issues in the past with the system, or compressor issues, metal can get into the system and settle in the evaporator and/or accumulator and affect performance. Also check to make sure the cooling fan is working properly. If it isn't, it won't provide enough air across the condenser to cool the high side charge. A symptom of this would be warmer air at idle, but a cooler air as you drive the truck.

Lastly, it could be a problem in the heater case itself such as a temp door and not letting all the cool air get to the proper place. This probably is least likely to be your issue if the low side line is only cool to the touch as you say. That really means you most likely have an issue with the components or the charge.


Re: How to find truck gear ratio

Your truck was available with about 5 different gear ratios, so there is NO guessing that's going to help you. If you don't have any documentation with the options for the truck, you're basically going to be left having the count the teeth on the ring and pinion.

If you choose to do that...count the teeth on both the ring and pinion gears and then divide the pinion number in the ring gear number to get your ratio.

For example: Pinion teeth = 11 Ring Gear teeth = 45 would be 45 divided by 11 = 4.09 gear ratio (would round up to a 4.10)


Re: 94 chevy starts than dies

Well, you really to get a gauge to test fuel pressure to be sure whether that is an issue or not. The fuel spray from the injector not being uniform is no big deal and not a correct way to try and diagnose a problem. Check for any vacuum leaks or other issues that cause starting problems or would add/take away fuel and air from the mixture. Throttle body gaskets are known for cracking and sucking air. Injectors have been known to become faulty. You really need a proper fuel pressure reading and then go from there.


Re: Silverado shakes and sputters at low speeds

Could be a low rpm misfire or other engine/fuel/ignition issue. I've seen burned valves cause a rough idle/low speed running and then be fine once you are on the gas. That would require some investigation, though, such as a compression check. Possibly a tune up is in order? Check fuel pressure and if there are any restrictions like a clogged fuel filter. Have any repairs been made recently?


hot fuel module

What is a hot fuel module on a Chevy Silverado and where is it located so I can replace it.


TRANS GOES TO LIMP MODE WHEN SHIFTING INTO THIRD GEAR

I HAVE A 99 SILVERADO THAT FLAGS A PO758 2/3 SHIFT SOLENIOD ELECTRICAL CODE. HAVE REPLACED 1/2 & 2/3 SHIFT SOLENIODS AND TRANS WIRING HARNESS ALSO SPEED SENSOR. CAN CLEAR CODE, START TEST DRIVE 1/2 SHIFT GOOD 2/3 GOOD THEN INSTANLY DTC APPEARS AND GOES INTO LIMP MODE. THERE IS NO DATA FOR TRANSMIISON READING ON SCANNER AT ANY TIME. ENGINE DATA IS ALL THERE AT ALL TIMES. SCANNER DOES HAVE THE CAPIBILITY TO CONTROL TRANS SHIFTS AT MY COMMAND. IF I STOP AND START TEST DRIVE IN COMMAND MODE THE TRANS WILL SHIFT UP AND DOWN WITH COMMANDS.THE FAILURE CODE DOES COME ON WITH 2/ 3 SHIFT COMMAND IN THIS MODE BUT WILL NOT EFFECT THE ABILITY TO SHIFT TRANS WITH SCAN TOOL IN COMMAND MODE. HAVE CHECKED AND RECHECKED POWER ON FUSES, POWER AND GROUND AT THE DATA CONNECTOR {GOOD}.


Having a Rear End problem- Silverado

I have a 2004 chevy Silverado and I have a roaring in the rear end. The first thought came to mind was that the rear bearings was going bad but I also thought that it would be unusual for a truck of this age to have the bearings go bad. I guess I should add; I have just over 64,000 miles on the odometer. What the possibilities? Or What could be happening?


Re: Truck idle high after throttle cleaning code P0121

This sometimes happens after a throttle bore cleaning due to the idle position that the computer has learned is now not correct. As the throttle builds up carbon deposits, the computer will re-calculate the idle position so it can get the appropriate amount of air to the engine. After a good cleaning, the old idle position is basically letting in too much air, hence the high idle.

What needs to be done is an idle learn reset, but this will require a scan tool. Sometimes driving it for a while, even up to a few hours, the idle will eventually relearn on it's own.

A few instances, which I've seen myself, the computer can't seem to compensate properly and needs to be reprogrammed to correct the issue. This again would require a scan tool and your local GM dealership.

Take it for a long drive, some highway and some stop and go driving. If this doesn't help, you'll need to either get the idle reset, or the computer reprogrammed.

Heres my problem. Most of the time when I try to start my truck it. Wont turn over. If I leave the key on the head lights flash and click. This will go on anywhere from 5 minutes to over an hour. Then the door looks will click the headlights stop flashing and the dome light comes on. Then it will start up?? I was also able to remove the key from the ignition while it was running.. The dealer thought it was a ignition problem and sold me a new ignition switch, a key lock cylinder and a case. I installed them last nite and I still have the same problem.... any ideas?? Thanks, Chad

2003 silverado ss brake issue

I hit a curb with my drivers side rear tire while drifting. It broke the rim and now the break pedal goes to the floor. There are no fluid leaks. They have been bled and I have checked the booster. The axle could be bent but thought that would cause pulsation. Is it possible the rotor was forced into the caliper pushing fluid back to the master cylinder blowing a seal. Any thoughts?

Strange Dash Light on 2005 Chevy 2500HD

I have an 05 2500HD crew cab and there is a light behind the dash just to the right of the Brake indicator. It stays dimly lit even when the vehicle is off which drains the battery if not run regularly. The bulb appears to not be behind any of the indicator templates. The light does not flash nor does it change intensity. Any ideas?

04 Chevy big block weird running problem

I got a 04 2500hd with the 8.1l motor. I had to replace the motor because the old motor was ran with no oil. I had it running great and put about 500 miles on the new motor. It was running great and I got up to go to school the next morning and went out to start it. it started fine and I went back inside for ten minutes and when I came back out it was idling rough, the check engine light started flashing so I didn't drive it that day. I ended up reading the codes from the computer and it was saying that cylinder 7 and 8 were miss firing at the same exact time I tested pressure and everything like that. then while trying to rev it a big clunking noise started like the timing was off. it also wouldn't rev above 3000rpm. it would just totally max out at that. what I don't understand is that I had it running great for about 500 miles before all this happened...I am extremely stumped and would like some advice. thanks

1995 chevy silverado wont idle and stalls when stopping

i have a 1995 silverado 5.7liter 350 engine, i replaced the motor,the other motor had 225,000plus miles. after replacing the motor it will not idle,and stalls out when stopping, also noticed that the motor surges, when applying the throttle it will rev up,but it will try to die off unless you let off accelerator a little and reapply. I had a trouble code of # 22 t.p.s, I replaced the throttle position sensor, m.a.p sensor, and the idle air control sensor,however i am still having the problem, it is throttle body injected, and there arent any other codes showing up.
Any help would be much appreciated.
