1998 Grand Prix stalls after 3 seconds

**dartrod** · 06-07-2011

Hi, I have a 1998 Grand Prix that stalls after 3 seconds. Hav replaced the MAF, fuel filter, and fuel pump. Have also also disconnected the aftermarket remote start.

Nothing has worked. there is a suggestion that the factory security system may be at fault.

Any Help would be appreciated.

In the underhood relay center, pull the high speed pump relay. Bend pin 85 out and put the relay back in place.

Does it stay running?

If so..it's the fuel pump resistor.
