Fuel pump fuse keeps blowing

Asked by Mar 30, 2016 at 08:16 PM about the 2001 Pontiac Grand Prix GTP

Question type: Maintenance & Repair

My 2001 grand prix gtp has been blowing fuel
pump fuse #32 every couple days. This seems to
happen if i park on a big incline or do a fair amount
of driving and come to a stop. I've noticed that the
relay beside the fuse is quite warm when the fuse
blows. I'm a student and really can't afford a costly
repair. I've just been swapping fuses when it blows
but i have to take my car 2 hours out of town in the
next month for a practicum that i absolutely
cannot miss and I'm worried about my car making
the journey.

The most common cause of this is a fuel pump drawing way too many amps, usually just before they quit completely. The other problem is a circuit problem ie, rubbed through wires, weak grounds at the fuel pump connector, bad relay, etc. I must say that you have set yourself up for a sure fire failure, it seems that there is a law of physics out there that if something is wrong with your vehicle it will manifest itself in the worst way possible when you out of your local area. If you can'y get it fixed before you go, how about a rental car or the bus UGGH but you gotta do what you gotta do.
