Thread: Prix starts right up and stalls

Ok so my Prix will start just fine and within 3-5 seconds will stall right out. Its seems to be security but the light comes on when I turn the key and is off when I go to the run position and stays off when I start it. I put the key in the run position and disconnected the battery for awhile and then tried it and nothing. Disconnected the MAF and still nothing. Don't smell any fuel at the FPR so I think its ok, pressure seems good as well at the rails. I also know the fuel pump reisitor might go bad and to bypass it you bend a tab on the fuel pump relay closest to the fender but my GT fuse box does not have that relay.

Car is a 00' GT with a 98' L67 swapped in, body has 189k and the motor about 135k

It seems something it killing the car the way its starts and shuts off but I can't figure out what so thought I'd post here. Any thoughts would be a major help, thanks.

Will it stay running if you give it gas?

It will not. Have started it at half throttle and full throttle as well and does the same thing.

Does it do the same thing with all of the keys you have for it?

Yea it does. Tried the extra key I had and even a valet one.

An ignition switch can cause this on all keys if the ring is going bad or went bad. Do you happen to have a tuner?

No tuner just a simple scan tool. Rained all day yesterday or I would of tried a few other things.

Pretty sure I found the problem and its the fuel pump resistor. Being I don't have the speed relay I just jumped the connector for it behind the battery and it will stay running. For sure can tell the pump is in High mode.

Hope my local dealer has a kit for it. Thanks for the help though guys.

Thought you were a GT w/o the relay in the fusebox. Which should keep it in high mode all the time.

Well I ended up plugging it back in and the car starts and runs again with no issues.. Maybe it was the security? I did leave the battery disconnected all night before I tired to jump it. Security light never flashed or stayed on though.
