(45 reports)

The fuel pump may fail causing the engine to stall and not restart.

Fuel pump stopped pumpimg without warning. Had car towed to my garage wgere they advised me fuel pump was defective. after replacing fuel ump it was discovered the fuse box under the rear seat was fried. Car was then toewd to the local dealer where fuse bx was replaced and reprograming was necessary. i checked for a recall and was told there was none. -
FUELPUMP RELAY BURNS OUT, X 3, DEALER REPLACED FUSE BOX, CLEANED BATT. TERMINALS, TRACED WIRES, REPLACED PUMP, AND NOW SAYS IT IS THE FUEL GUAGE SENDER THAT IS BLOWING RELAY. GUESS WHAT; THEY WANT TO MAKE ME PAY FOR ALL THIS WORK. HAD TO HAVE CAR TOWED TWICE, DEALER WOULD NOT GIVE ME A SPARE RELAY SO I WOULD NOT HAVE TO HAVE IT TOWED. I WAS THE ONE WHO BROUGHT THE HOT RELAY PROBLEM TO THEIR ATTENTION. THIS IS A TIME BOOM WAITING TO HAPPEN. BURNING RELAY NEXT TO BATTERY UNDER BACK SEAT. -
same issue. would crank but not start. The fuel pump and relay were replaced and not even a month later, the relay melted from who knows what. i talked to the mechanic that fixed it again and he stated that the fusebox or module has problems with it that may be an engineering flaw. -
Stop and tried to start the car and it would not. It was traced to a bad fuel pump- car has abt 66,000 miles -
2 weeks ago, went to start vehicle and it was not getting gas. Had it towed and diagnosed as fuel pump. Had pump and relay replaced (relay was melted). 2 weeks later, I went to start the vehicle, same problem. Had car towed again and once again the relay is fried. Mechanic opened up fuse box and seems to be an electrical problem where too much power is going to the relay causing overheating and pump failure. -
Fuel pump failed and replaced. One month later it failed again. Turned out the fuse panel under the backseat was overheating and meeting causing short to the fuel pump. Mechanic said that box should never need maintenance. Buick refused to speak to me about problem. -
Car wouldn't start, checked fuel pump it stopped working also relay was burnt & melted a little. Replaced fuel pump and relay. Drove for @20 miles the car cut off and the new relay had melted. Put in another relay and the car started but i noticed the fuse box and relay was very hot to the touch. May have to replace fuse box before my fuel pump blows again -
Went to start car, didn't start. fuel pump drew down too many amps and burned fuel pump module had to replace fuel pump, fuel pump module and electronic injector. -

Same issue as everyone else with the fuel pump and relay box burning up. It seems to be a design weakness. -
car wouldn't start. checked fuel pump 20 amp fuse checked o.k. pulled the fuel pump relay had some burning on the bottom and on fuse block replaced relay and fuse block o.k now. why is there a 20 amp fuse when fuel pump draws 4.1 amps? -
it was 4x now that car won't restart after it was just been used. days after it start again. we have the fuel pump changed and it still happen. I am scared to use the care even if it start in-case it won't start again when i go home from work. The technician from the dealership have check on it but couldn't find anything wrong even that they have to pick up my car from work but it start on them. my husband has to drive early in the morning to pick me up and he also tried starting the car but failed to start it. Two hours later when the dealership came to pick the car it start but they still check it in their shop but couldn't find anything wrong. -
car cranks but no fuel to engine got towed dealer says fried fuse box I have read many people with same issue GM should racall Dealer charging me $530.15 to fix I think GM should pay what does anyone else think. -
Engine cranks but will not start. Seems like it isn't getting fuel -
fuel pump went out for third time today, and probably burnt box again under seat as with the first two times.Also replaced the motor mounts before and one is broken again. I won't have this problem after I get the car fixed this time because I will be driving a japanese car! -

Fuel pump relay went through a meltdown taking the fuse block with it... they said the fuel pump is ok and not drawing to many amps but I wonder. -
