94 pontiac bonneville starts and runs good going down the road. When you stop at the store and cut it off it won't start back up for awhile. Change the camshaft sensor, igintion module, oil pressue gauge unit. What else can it be. It gets fuel but no fire. Spark plugs, wires, etc has all been changed.

Try an ignition coil, they can work ok till they get hot, then nothing. Also check to see if the theft light is on when it won't start. I know this May sound strange, but does it have tilt wheel and do you use it?

Fixexpert, Hondachopper, RonaldSuboc, Kevin000, Chad7, please step off, you are ALL WRONG, and your info is 100% USELESS.
If you HAD ANY experience re this issue, you would KNOW THE FOLLOWING:

Kkvesr, What you need to look for, is the main ECU ground point at the LF rocker panel rail; lift the carpet to see this, between the seat and the rocker...there are several wires going to a corrugated "star washer". If you are NOT getting a ground pulse in the RED wire, your main ECU ground, at the wire position described above, may be corroded. if so, no injection.
This is a very common problem, unique to the Bonneville.
Please advise me if this helps, and thanks for choosing FixYa.

Change your coil pack. If you want to save money, go to an auto wrecker and get one. Don't be afraid of used parts. You drive on them every day. Might as well grab a mass air flow sensor while you're there.

It could be that you have picked up a batch of dirty fuel that has clogged the gauze input filter that is part ot the fuel pump inside the fuel tank.

Car cuts off going down the road

I would take a look at the throttle position sensor being faulty, but I can't explain why there is the only one fault code. Hope this helps. Good luck.
