Re: Grand Am remote start issue

that does sound weird, but I am curious, why are you disconnecting your battery? If this only happens when you disconnect your battery ground connection, that should happen every 5 or 6 years right? Once you replace your battery you shouldn't have to disconnect it until the battery goes dead in 5-6 years...



If it is the remote start feature that is reacting to the battery being disconnected you can try disconnecting the remote starting feature. You can do that through the DIC (driver information center)



PERSONAL PROGRAMMING MODE:This menu allows you to customize several features on your vehicle. These adjustments can only be made while the vehicle is in PARK (P). Press the set/reset button to display the first screen.

Press the options button (the one that has "i" in a circle) to access modes. scroll down until you get to remote start. If your vehicle has the remote start option, you can disable it here.

REMOTE START: If your vehicle has the remote start feature, this screen allows this feature to be turned OFF or ON. The remote start feature allows you to start the engine from outside of the vehicle using your remote keyless entry transmitter. See “Remote Vehicle Start” under Remote Keyless Entry System Operation on page 2-4 of your owners manual for more information. If OFF is selected, the remote start feature will be disabled. If ON is selected, the remote start feature will be enabled. To program this mode, use the following procedure:1. Press the set/reset button to scroll to OFF or ON.2. Press the options button again to advance to the next screen. PROGRAMMING FINISHED will appear on the next screen. This confirms that the personal options programming is complete. DISPLAY OFF will appear on the next screen. The screen will count down and then go blank. Press the options button to advance to a new screen.


Re: 02 grand prix gtp

boost control solenoid is controlled by the PCM. If you have boost at idle I would be checking the vacuum lines. Check the bypass valve actuator and the bypass valve for sticking or just stuck. Of a bad boost control solenoid.



to check the system for operation you will need a vacuum gauge and a scanner that can communicate with the PCM and you can tell the PCM to open and close the vacuum to the system. A vacuum pump would also help so you can apply vacuum and see if you can make the bypass valve actuator retract.



Have you hooked up a scanner to see what the PCM is doing? Do you have any codes stored in memory? If you do what are the code numbers?



why did you replace all those parts? are you having other problems other than just the boost gauge showing boost at the wrong times?


1998 pontiac bonneville security light flashing

Hello I have a 1998 pontiac bonneville and it isn't starting. It has a brand new starter and the battery if charger around 700. The security light is flashing constantly whenever I place the key in the run position but it doesn't do anything else. I tried doing the 10 min on run than 5 second off and repeating 2 more times like I was told but it didn't do anything. Is their any way to fix it or does it have to be took to a mechanic.


Rockers

2000 Pontiac grand am gt ram air 3400sfi rocker arm torque specs in ft lb?


Re: thermostat

okay, did you have a question about something?


Re: Grand Am rough idle

you really need to drive with a scanner on the vehicle. You need to see if the trans is slipping or shifting gears. If you are moving and s steady speed but your rpm changes then the engine reved up without changing speed. That's something inn the drive chain changing.



Knocking sound, well, that's something that someone needs to hear. I would suggest taking it to a local shop and ask if they can come out and listen to the noise. So many things is could be without knowing what it sounds like or where it might be coming from.



the knocking and the hard shifts may or may not be related. What about the title of this post? Does it have a rough Idle too? Is the check engine light on?


oil leak in Pontiac Firebird 3800 v6

i have an oil leak coming from the switch located on the front of the motor right above the oil filter.

is this the oil pressure switch?


Shift solenoid code P0752

Got a code of p0752 on my 2004 Pontiac Bonneville...v6 3800 series.


Re: Is there a right and left rocker arm

the rockers should all be the same but on some engines the push rods are different lengths. If you re-use the valve components you should keep the push rods and the rocker so that you put them back in the same position as they were originally.



year, make, model and engine would help. Pontiac 3.4L has intake and exhaust push rods that are different lengths.


Re: Grommets

not sure what you are talking about. the push rods just drop in on top of the lifters. The grommets you are talking about, are they the valve seals? When you buy a head gasket set they usually come with the valve stem seals. If you are replacing the heads you don't need those. the replacement head should have those on it. If you got complete heads. If you get just a bare head (no valves in it) then you would install the new valves and valve stem seals before you install the valve springs and keepers.



the push rods sit on top of the lifters. the lifters sit in holes in the block. There nothing over the lifters that holds grommets in place for the push rods. So, no torque specs.



IT KEY THAT YOU PLACE THE PUSH RODS IN CORRECTLY. INTAKE AND EXHAUST PUSH RODS ARE DIFFERENT LENGTHS. THE EXHAUST PUSH RODS ARE 1/4 INCH LONGER THAN THE INTAKE. iNTAKE =146MM (5.75 IN) AND THE EXHAUST = 152.51MM (6.0 IN).



you might know that already but just in case... I have had cars towed in that did not get them in right and the car doesn't run. If they are lucky they may have bent push rods. If they are not so lucky they have bent valves.



Or I may be mistaken. I don't know of any grommets for the push rods but I don't know everything. At least that's what my family says


Pontiac Grand am GT Coolant leak

I have a coolant leak on the passengers side of my 1998 Pontiac Grand Am GT 3.1. I have replaced the intake gaskets and also the water pump but it is still leaking. It leaked just refilling the coolant and not even running. It is leaking on the passengers side from some where above and on the backside of the crankshaft. I also now developed a leak from it seems under the radiator (new leak after putting everything back in except battery)

Where are the coolant elbows located as I have heard they are notorious for cracking. Or could it be the timing chain gaskets, if so how much work am I looking at?

Thank you for your help


2001 Grand am vent valve wire

I plug my scanner in and gave me 0449. Went under car and realized someone replaced vent valve solonoid. Held up by small zip tie. The valve part was broke off and wires from solonoid looked as if they went when valve went. Where do they go to. I see a 3 plug assembly. One had no wires so am I correct to think of goes there? I connected test light and tried across prongs and to ground from that plug. No light. Ideas?


Re: Shuts off when at normal temp

sounds like the time where the computer is supposed to take over (normal operating temp.) it doesn't have some parameter it's looking for. You need to have a graphable scanner hooked up to your vehicle and see what happens when it reaches normal temp.



check to see if your engine temp is -40F. if the temp sensor is open it will go to -40f


Re: 1998 Pontiac grand am gt 3100

It's very hard to tell you about something that I can't see. A coolant leak follows a path that is the easiest to go down. It may zigzag down as gravity pulls it. Your best bet is to have someone with an angled mirror and a flashlight look at your engine while it is leaking. Water outlet, intake gasket, coolant hose adapter are all common leaks.


Re: Starter fuse

fuse #54 should be the crank fuse. It only shows that it is connected to the powertrain control module and the park/neutral position switch. You might have to take it to a shop unless you can locate the wiring out of the fuse block and separate the wires to the pcm Pin B11 purple wire and the neutral safety wire pin A11 yellow wire and check each wire with a 10A fuse and see which one blows the fuse and then trace it from there. Have you added any electrical equipment or made any changes to the vehicle wiring? Check the wiring going to the neutral safety switch and see if it has rubbed through any where or is pinched somewhere.


Re: Location of oil pressure sensor

here is a picture of where it should be Item #2


2005 Pontiac Vibe --No tail lights

My 2005 Vibe all of a sudden now has no tail lights. I have replaced the DRL relay, head light relay, tail light relay along with bulbs and fuses and still no tail lights. The dash lights are super bright with no adjustment.


Making sure of oil flowing freely before reassembly

I have a 2001 Pontiac Grand Prix GTP and im just right about to the point of installing the new bearing after fixing up the crankshaft, journals, and using the plastigage to get my bearing clearances. However, now Im back online researching the possibilty of the oil not flowing through system freely because of any small metal particles that might be clogged in there somewhere. There were some in the bottom of oil pan when i cleaned it out. I did read the post regarding 'Engine Oiling System Operation' and how in the event of there being a clog somewhere where the flow gets restricted there are ways set up in system to continue operation. Thank you for that info. Sooooo, just wanting to know if there are any other critical points of measure to take note before I start reassembling?


Blend air door doesn't move

1999 Bonneville SLE- how do I access the passenger side blend air door actuator? Through the glove box or by removing the radio and automatic climate control unit? Thanks, glad I found this site!


ABS ,tc brake light ,NO connection?

I have a 2004 grand prix GTP My problem is the brake , abs , traction control , lights are all on . I have a OTC Genisys scanner It should read and clear all codes , but it don't log on to the abs,brake system at all? That part is totally dead . it don't read at all. Everything else it logs on fine. My question is . Does the body control module handle the abs, tc, brake program? It don't tell me anything ? Or is it the ABS module that sends that signal OR the pcm main computer? I was thinking of replacing the main computer ,pcm . but i don't want to buy something i do not need'' It still has the original ignition switch. If that helps.

I found allot of other past codes , but are they related to the abs function? [ checked and cleaned grounds ,battery connections good , all fuses are good and relays , all connections pcm, brake module are good . Please can anyone help!!! There is a problem listed like mine but again not the same '' Thank's

83 grand prix no start

car ran fine yesterday. wont start today, not getting fuel into carb,fuel pump ok and changed fuel filter. will try to start if primed with gas. any help would be great. thanks


Re: Pontiac Sunfire trac off light

Yeah, take it back to them and have them fix it. They obviously messed something up. You shouldn't even be on here asking such a question, you should be back at the place that repaired your car and raising hell. That's the trouble with independent shops and other non-dealer repair facilities....always a bunch of hacks.
