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.

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

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.

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.

engine cranked and seemed to start then quit within a second. Dealer put the scope on my engine and reported fuel pump and relay needed replacing.
2008 Buick Lucerne - V6 68,500 mi,
engine cranks but won't start. Fuel pump relay was melted. Replaced relay, drove 20 minutes, then lost acceleration and power steering. All fuses and relays intact, but the fuel pump relay was very hot to the touch. Taking to a mechanic tomorrow, this should be a manufacturer recall. Absolutely ridiculous to have this problem.
