my 2000 grand prix starts but immediately stalls out after about 7 seconds by ljm1667

I recently have been having a problem with my grand prix that no one can figure out. about a month ago i started up my grand prix and it stalled out after about 7 seconds, it kept doing this so I had it towed to a local service center. I was told it was my fuel injector and regulator. Both were replaced and the car started. I took my car home and about an hour later I started it up and it again stalled out after a couple of seconds. At this time I now had the car towed to a dealer who had it for two weeks. They told me that my fuse box was bad and they replaced it. They guaranteed me that this was the problem. $1400.00 dollars later I got my car back. I was able to drive it for two days with no issues. Again I got in my car to go to work and it started up for a couple of seconds and stalled. I was thinking there was an issue w/ my security system but the dealer said that was not it. Does anyone know what could be wrong with my car. I have had no problems with this car until now. My pocket book is getting slimmer everytime it is at the dealer. Any suggestions on what is wrong with it would be greatly appreciated.
 
thanks !

Any ideas what the problem was? My 98 Grand Prix is in the shop at this very moment and the mechanics are stumped.

Check the fuel pump resistor, a common issue on supercharged engines. Most likely it will run if you hold it floored, but a common issue.

I just got my 200 GP GT back from the dealer after the same issue. It turned out to be the Theft Deterrent Module $560. They said their is no way around it. GM had a bulletin out that said the wires were prone to chafing. I hope this helps.

hey bud, well i dont know if this is much help but my buddie was having the same problem. next time this happens to you un hook your battery for about ten miutes then put back together and see if it still happens if this works them it has something to do with your security system . thats what happend to my buddy grand prix ( i know it sounds stupid buy hey its worth a try )

fuel level gauge not reading correctly by bowerdh

Has anyone delt with the level indicator going from full to empty and not reading anything in between? looking at the part (fuel pump) the sending unit is a part of the pump. I am currently going through the ignition switch replacement due to the heater fan and the console going out (thanks for the info. on this site) and was courious if some one else has had similar issues.

I am having problems with my 2002 pontiac grand prix. I lose acceleration on hills when i push the gas pedal the rpms go up but i lose acceleration. Today coming home I slowed to turn on to my road off highway and it died. I got it started after a bit and got it almost home but had to slow down and it died again. I was thinking fuel pump or filter? Any suggestions?
Thanks
