WONT STAY RUNNING! Any Ideas about this

**2001** · 12-17-2011

2001 GTP
when started it will cut off after about 5 seconds.
i can start it and push the gas pedal and it will stay running until I let off the gas.

I have changed the gas pump in the tank.
I have swapped the computer with another car I have.
I have checked all the fuses.
Any other ideas on this
Thanks

Welcome to GPF!

Put your factory PCM Back in. Is your check engine light on?

Sounds like a vac leak or fuel filter problem!

i have a 02 GT and i have the same problem. It just started yesterday. sometimes it will start right away and sometimes it will start then it will die within 5 sec or so. if i try again, it'll start right away. I have no check engine light on but i do need a tune-up so thats probably the problem.

Moved thread.

Please post in the correct section for your topic.

Mass air flow sensor maybe? I had one that was doing the same thing. I was told thaat, that was the problem. I replaced it and it ran fine.

1. Hook up a scanner and check for codes.
2. Check your intake filter for obstructions, like leaves, mouse nests, or homeless people. This could halt air flow to the engine. It's a 30,000 mile part, so worth replacing.
3. If it's been 30,000 miles or more since your last fuel filter change, do that. After 30,000 miles, they begin to clog up and keep fuel from getting to the engine, as well as burn out the fuel pump.
4. Make sure the mass airflow (MAF) sensor in the throttlebody is fully plugged in. A loose plug could result in a voltage issue.
5. Clean the MAF with CRC Mass Airflow Sensor Cleaner. A dirty MAF can lead to the wrong information about airflow causing the wrong fuel and spark to happen.
6. Check the throttlebody for gummy filth. If it's dirty, clean it with throttlebody cleaner. A gummy throttlebody plate could be getting stuck or not be letting in the right amount of air.
7. Pull out your spark plugs and check them. They should be clean with a gap (check this gently!) at .60". Stock spark plugs are supposed to last 100,000 miles and not an inch more. If you're close, it's worth putting in a fresh set of stock iridium spark plugs. A set of stock spark plug wires are also cheap insurance.
8. You could have some sort of severe vacuum leak. I'd venture to guess if it's killing the engine, you could fit a rolled-up magazine into the hole.
9. You might have a stuck injector. It could be stuck open or closed, either starving the cylinder or flooding it with fuel.

I have swapped the computer with another car I have.

In case this is as simple as it sounds, you can't just pull a PCM from one car and put it in another and have it work without any modification.

sometimes the security system needs to be reset. turn the switch on and off 4 times, then start and let it die, leave key on for 15 minutes and then try to restart.
