Hmmm,
 
Furnaceman, to be honest with you I dont know what else it could be. I dont think its the starter or alternator. I would suggest taking it to either your mechanic or another one for a 2nd opinion. Also, try using Google and type in the search "starting issues with 1988 pontiac" and research some of the links it provides. You may find an answer there as well.
 
Wish I could've been more help. If I should hear anything I'll be sure to share.

No, it doens't have any problems charging or turning over, it will crank as long as I want when it won't start, it just doesn't actually start.
 
 Thanks for the Google idea, I suspect I will be finding another mechanic for actually a 3rd opinion.

Have you tried engine cleaners to clean carbon deposits and sludge in the engine? In an engine that old you are likely to have a lot of it.

Not entirely sure how I can have a carbon deposit that can cause a problem sometimes? Also it only has 62,000 miles on it. Also not sure how this can cause it to not start after it gets warm but cause it to start after it cools for a couple hours?

Hello Pdilcher,
 
can you provide a few details on what happened? What did your car do before it had the problem or what signs did it give? What does it do when you turn the key to start it? A few things to check would be the alternator, check your fuse panel under the hood and in the cabin of the car. Also check your fuel rail to make sure you are getting gas. You can do this by locating a small nozzle that has a cap that you would turn to take off, then you should see a small pin, press that pin down to see if fuel comes out. Make sure you do this with the key in the on position so that the fuel pump is on. Start by checking these few items 1st.

My niece has a 2004 Grand Prix GTX. It will die intermittently. All electrical goes off and no codes. I am thinking it might be a bad circuit breaker and maybe an intermittent short. The circuit breaker might be tripping and then resets when it cools down enough.

#327 of 360 2002 Pontiac Grand Prix Keeps Cutting Off Please Help by gw76

Aug 25, 2012 (8:46 pm)

I have a 2002 Ponitac Grand Prix it keeps cutting off. I took it to the shop and they said they couldn't find anything wrong with it, but clearly there is something wrong. It cuts off if I am driving it in traffic, it cuts off if I am sitting idle such as in a drive through, it often cuts off as soon as I start it and then I have to start up again. Sometimes when I am sitting idle it starts to cut off and then it seems to like catch itself and jerks back on. There are times when I start it that it literally jerks when it starts.....PLEASE any ideas why this is happening and what this might be? Please respond....

Hello GW,
 
Here are a few things to check before you take your car out again. Check your antifreeze levels and your temp gauge when you are driving to make sure your car isnt overheating. Also, when you turn your key into the on position without starting it, turn down your radio and have the door closed and leave the key in that position for a moment to see if you hear the hum of the fuel pump. You should hear it hum consistently. Also, when is the last time you had a tuneup performed? Lastly, I had a similar problem with mine and it turned out to be the connectors to my fuel pump were going bad. You can access your fuel pump thru your trunk bed I believe. I dont think Pontiac changed that considering I have an 04 GTP. Pull back the liner, you'll see a metal plate with about 8 screws, take off the nuts and lift off the plate. You'll see the connectors running to the pump. Turn your key to the on position without starting it, then kinda move the wires with your hand just a bit to see if the pump cuts off or continues to hum. Lastly, in some cases it could be a crank and or cam sensor. Try checking the other items 1st, hopefully this can help you use a process of elimination.
 
Hope this helps.
