grand prix wont stay running!!

**fremmy182** · 01-21-2013

so i posted before about my fuel pump not turning on. It ended up being the orange wire that poweres the PCM. It was burnt and fryed off. So i replaced it and when the car was in the on position all my dash lights were normal, fuel pump was turning on. I couldnt be happier. I tried starting the car and the rpms go up to 1000 and the car just dies. i tried jumping it and the same thing happened. While I started it again i held the gas pedal and the rpms stayed up. but died once i let go of the pedal. Whats wrong with my car now, I thought i fixed the problem now its something else :-(. If anyone can help that would be awesome, thanks guys

IAC valve or TPS sensor maybe.

**fremmy182** · 01-21-2013

I dont even know where those are located.. But I never replaced my fuel filter before and i have 135k miles. So im going to replace that first.

Idle air control and Throttle position sensor is what he is talking about.

Google them and you'll find out.

Do you have fuel pressure?

**dsmuts** · 01-21-2013

Try unplugging your maf sensor.

good luck... 135k that line is not going to break free.. im sure its rotted right into the filter. im sure thats not your problem anyway but you should try to change it for maintenance. check for fuel pressure... id put money on that its your fuel pump resistor.

if the fuel pump resistor is in my fender, how do I get that thing out? Im definitely not taking the fender off lol

**joe0813** · 01-22-2013

you can try to by pass it and see if the car will stay running.

**joe0813** · 01-22-2013

and you dont need to take the fender out to get it. its right on the frame rail ... pull the wheel well out enough to be able to look up there.. its white so it stands out

Turns out it was the IAC valve, thank you all so much for helping me get this car back up and running. I will be selling it soon.. anyone want to take it off my hands?
