ok, I understand "turn off" as a engine stall. "will not let me turn it back on" what does that mean? Does the engine crank over but won't start? The engine won't turn over in the start position?



so, first thing, starter working or not? If starter turns the engine over the battery and charging system should be okay.



In most cases, the battery that starts an engine won't be the problem. If there is enough power to start the engine once, there is more than enough power to keep it running. the starter take a lot of amps pushed by voltage to turn the engine over. It doesn't take that much power to keep it running. You shouldn't disconnect the battery with the engine running. Charging systems look for the battery voltage to know how much to charge the battery. No battery voltage sensed could cause a charging system spike that could damage components.



You may have caused codes to be stored that are not related to the problem with your stall and no restart. You need to scan for codes and then go in and clear all codes. then try and see if you still have the stall- no restart problem. If it is still there, now you scan for codes to see if there are any codes that should be specific to the problem. If no codes are stored but the problem still exists you will need to use a scanner that can show you data stream of the engine controls. Looking at the data stream while the engine won't restart will let you see if all the parameters for engine running are correct. Crank, cam, fuel, air flow, purge and vent valves, ect.



other things that could cause a stall and no restart is a shorted component. A shorted fuel injector, ignition coil, engine sensor...



Fuel pressure could also cause a problem like this. When you first turn the car on, the fuel pump turns on and primes the fuel lines then you crank the engine over and the fuel injectors shoot fuel in the engine to run. If your fuel pressure is low (too low to run) you could get fuel into the engine from the prime that will start the engine but then without enough to keep the engine running.



does your vehicle have a turn the key to start or is it push button start? Does your vehicle have a security light on? Is this a problem that happens sometimes of is this a condition that has completely disabled your car. (can't get it to stay running at all)



How is the battery in your remote?



can you give ma a step by stem description of what you do and what happens when you have this problem? or a video on youtube or something so I could actually see what is happening...

Took my 2002 Ford explorer to get a smog repair on May 1st I had replaced the intake manifold due to coolant leak from what appear to be the coils or even perhaps the thermostat,

But upon turning the key to start the vehicle there was a crank but no start so this is the reason why I took the vehicle to the mechanic for the smog repair.

They call within an hour and say tabs off the ignition coils were broken they said they took off the manifold to make sure I put on the gaskets correctly but the gaskets are attached to the new manifold so there was no reason for that there was a vacuum leak so they torqued down the manifold 'correctly', they said that I had the thermostat gasket on incorrectly so they redid this for me they checked all my hoses and did a full inspection and my car cleared for smog.

300 mi later I was driving on the freeway and from what they said a spark plug blew, and I needed a replacement so I took truck back to this mechanic and they told me they had to rethread the hole for the new spark plug.

So within a month I spent over $1,000 with this mechanic,

So somewhat 3 weeks ago and 500 MIles into a 24,000 mi warranty,

I have coolant all over my manifold once again appears to be coming out the thermostat again one of the injector coils in the front of the fuel rail was missing the setting bolt, and car will not start, not even crank, my battery seems to be draining, and when I was troubleshooting the starting relay I swapped fuses with the blowing motor, before the swap car would take slowly, now after the swap I have a rapid tick coming from nearest to the steering column yet still under the hood of the car, doesn't sound nowhere near the starter or the starter solenoid, not even the fuse box.

Any ideas,?

Car lights still work radio still works

Hi,



Ive been chasing a misfire in this car for quite some time. It doesnt give me a code for this. The misfire is almost always at low rpms, or when initially accelerating. At first start, i put into reverse it stalls. I restart it, then it drives ok, or sometimes does this misfire thing or it will accellerate slightly without me hitting the gas. I assume this is a vacuume leak. I have replaced: fuel pump, fuel filter, sparkplugs, upper intake manifold gaskets, vent canister solenoid, cleaned canister as well, cleaned fuel injectors( all are functioning) replaced all noticable vacuum connections and hoses that Im aware of. Did a fuel pressure test which shows the fpr is functioning, but the pressure is only 38 psi. I recently replaced the IAC, and notice surging issues with it after a drive, it doesnt seem to reset so I ordered another one. Ive tested these sensors and they are functioning:MAP, MAF, TPS. I have tested the resistance on the coil packs, but dont know what the specs are for them, I dont think they are the issue.

There are trans codes 0716, 0741 , p1689, p1887, but I can reset the battery and the car will operate fine for a time. Ive even replaced a bad wire in the trans harness

I really want to address this misfire, is there anywhere else I may have missed a leak?

Is the transmission causing the misfire?

I have a 1994 Olds Cutlass Supreme S 3.1 and back in Feb my cut was cutting off while making a slow turn, but started back up; took it to Firestone to check it.They checked stater, battery, alternator and they were ok, but they tried to replace a IAC and sensor, didn't work,they cleaned the throttle body, didn't work either. Took it back to them and this time they put it on a scanner and it needed a CRANKSHAFT SENSOR,so took it to another shop and they put one on,but it doing the samething , but worse.In short, they have put in another EGR, cleaned the fuel injectors a new alternator, which was running over 15volts, now I need something called a A/T CONTROL SOLENOID, but MEKINIE says they don't install this,but I had a transmission installed by them back in 2014 or15.I was told by the manager that ANY part they put in I don't have to pay for cause of the CRANKSHAFT SENSOR they put in.What should Firestone should have checked out 1st? And do a A/T CONTROL SOLENOID sound right?

Hi I have a great wall x240 the 4wd light is staying on an it sounds like it's not trying to engage at all any help is appreciated thanks

5 minutes into driving- loss of power,random misfire(P0300 code). towed car home. Installed gauge in pressure sensor location and needle would not move. 3+ quarts oil drained from pan. Removed,disassembled and inspected pump-no scoring or obvious damage. What else should I inspect?

Thank you

I have a 2002 Oldsmobile Bravada with a 4.2 Vortex. Could you please explain where my pcv valve is located? Please and thank you.

Hello. I recently charged my a.c. on 3.5 intrigue & stupid me starting putting it in wrong port. No big damage. Did find right low service port next to the one. So I want to know what port did I mistake or for. Its along firewall with green cap, behind brake fluid fill. See pic. [attachment=0]PICT1302-640x487.jpg[/attachment]

02 olds silhoutte at first it would not start have gas and spark then for no reason it starts but idles at 2k now gas and temp gauge radiator fans ac clutch dont work thanks jp.

the fuel pressure should go up a little bit when you disconnect the vacuum line to the regulator but that is while the engine is running. If you have a rubber return line you could pinch off the return hose and get a deadhead fuel pressure. that would tell you is the regulator is reducing the fuel pumps pressure from the tank of if the pump is maxed out. But like I said before 38 psi is below spec but it should be enough to make the engine stay running. Should be anyways.



while 95 might not be obd2 it should still have the obd1 connector. OBD1 should have the 12 pin connector and the OBD2 should have the 16 pin connector. this is the obd1 connector.

Think it's the bcm but some time the gauges come on when I try to turn ac or Windows they got off. Car running good 2002 Oldsmobile alero if I reset it by disconnecting both sides of battery and clap them together for 15 minutes will that help or do I have to have the bcm cleaned or replaced

I just picked up this 2004 Alero with 51K miles. The car is literally like new except for these couple issues. I'm not sure if they are related or not. Everything is stock original. Here's the scenarios:



LOCKS:

Start engine, put in drive

Doors automatically lock

Stop car, put in park, kill engine

Doors will NOT unlock automatically



RADIO:

Turn key to on position or start engine

Radio plays and works perfectly

With radio "on", turn key to off position, remove key, open door

Radio still plays,

Get out of car and lock doors with remote, radio still is on.

unlock doors with remote, open and shut door(s), re-lock doors with remote,

radio then turns off.



Can someone please tell me what to check to solve these two issues? This is my sons first car and I want to make sure these issues are fixed before I turn it over to him.



Thanks

Have what they call a "throw away" Cutlass that started running rough. Long story short the car will now start and idle when you step on the gas it will rev to 2000/2500 rpms then start backfiring and sputtering. I have replaced the fuel pump, fuel filter, EGR valve, map sensor, spark plugs, coil pack, pressure regulator, manifold gaskets, have checked and cleaned the catalytic converter, and checked the relay fuse. Problem is the car has no power, Can't get it to go. Any ideas what the problem is or what else I can do. Please and thank you for any suggestions.

One day I turned my car off and it wouldn't start back up when I turn the switch over the dash gades work but it won't turn over or make a noise, then my dash light went out then a could days later my tail lights went out, my head lights, blinkers, brake lights work! I can figure out what to do about it not starting and what could be wrong with the dash and tail lights, fuses are good!!

My '93 Cutlass (3.1 port injected) runs very rich all the time. It blows black smoke and stopped up the cat converter which I removed. It starts easily every time. Sometimes the check engine is on, while at others it's not. MAP sensor, fuel pressure regulator and ox sensor have been replaced. Sometimes the engine will stall at up to 20 mph. I want to get it where it runs ok and then I will replace the cat. It always seems to run on all 6 cylinders and has normal power. At times it bucks on light throttle at speeds around 60 on level ground. Emissions testing is due in 2 months, so a solution is needed soon.

Question on over heating on a 99 Olero 3.4 , I have put in a new thermostat , new radiator cap , & a new fan relay module & still over heats , only thing left is the PCM ? Thanks inadvanced

hi

I am trying to find how to replace my drivers side mirror with backing plate only. Is there any where I can just get that. I have the housing unit attached.

Where do I find the door lock relay assembly in my mothers 1995 delta 98

I need a fuse that is not for sale at auto zone so it might be that the truck is so old?

If you know of a site or place please let me know

thanks and have a blessed day!

my car was overheating and the fans were not working so I had it looked at and found that there was a short in the wiring to the coolant sensor so he disconnected the wiring and the fans came on. he said it was safe to drive the car until fixed. After driving it the first time I found a little water leaking from cap even though car was not hot so replaced the cap and its find. My question is what are the dangers if any in driving with the sensor disconnected? How long?

thanks,

Have a blessed day

I have a 2002 Olds Bravada I bought during cold weather.The ac works good sitting in driveway but the second I put it in gear it blows the ac fuse.Not sure where to start looking for the problem.Any suggestions?

before you replace anymore parts you should have it checked when it won't start. When it won't start, you need to measure your fuel pressure. it should be 40 to 47 psi for the 3.8L. If fuel pressure turns out okay, check for spark. If the spark is good then check for fuel injector pulse.



each part will have it's own tree to follow depending on what results you get. Crank sensor, ignition module, fuel pump connector, shorting injector, passlock problem, coil pack, and on and on.



what is the problem you are having now? does it die while you are driving and not restart or is it you drive around and park it and it won't start when you come back to the car? Or is it both.

My car radio switched 12+ wire: yellow is only putting out 6.5-7 volts when I turn it up it goes down to 5v. When this happens my radio freaks out, stops playing, and makes a high pitched squeel. I turn my car off and the voltage stays the same and keeps making the high pitched squeel even with no actual power goin to the radio. When I turn car back on it makes an even higher pitched squeel and then goes back to kinda normal. By that I mean the 6.5-7 volts. It will keep doing this every time I turn my radio up to listening volume. Is there any way to get the wire back to 12v or a way to splice power onto the yellow wire from another wire? Like the orange constant? Please help

Where is the ESC module on a 93 Oldsmobile Cutlass Supreme?

I have a 2000 automobile intrigued in it want start but i took my battery to auto zone to charge it up in i did in i put back in the car in it still not starting but everything else work
