99 Grand Prix GTP starts and stalls

10

Asked by May 29, 2011 at 05:42 PM about the 1999 Pontiac Grand Prix

Question type: Maintenance & Repair

It's a 3.8, approx 110K miles.  Check engine light came on this week.  Now car starts and stalls, won't stay running, even with gas.  Indicated it was mass air flow sensor.  Changed MAF and idle air control valve.  After switching IAC, started better, but still stalled.  Would appreciate any suggestions.  No other car problems since I've owned it (4 years).  Thanks

For anyone else having this problem, I just want you to know it was the fuel pump resistor. It can easily be bypassed. Beware though, it's very hard on your fuel pump, so do not continue to drive your car on bypass. However, it will get you back to driving so that you can grab parts, go to work, etc. Just relocate and replace resistor asap. Relocation kit is ~$50.
