There had been no indication of a problem with the fuel pump at all. It was a normal winter night for me, went to pick up my friends from work, and decided to drive to one of their houses for a change of clothing quickly. I turned into my friend's and all of a sudden all my meters dropped to zero, I lost my power steering, and the gas/brake pedals were unresponsive. I managed to coast into the end of the close, half on the sidewalk (behind someone's parked truck on his driveway - oops) half on the street. It was very late in the night, so luckily there was no issues with said truck owner.

I called the tow truck and got my car towed first thing in the morning with AMA. Fortunately, the garage I took my car to was able to identify the problem & replace the part before 12pm. However, had the part not been in town, I would have had to wait until that part came in (a day or more?) and the car was obviously completely undrivable. I was lucky in that I was at very low speed when the fuel pump broke, if I hadn't been, like moments before, the results could have been disastrous. So overall it was a pain in the butt & a good dent in the old pocketbook.

I was driving on a busy highway in the middle of nowhere when my car started hesitating. As soon as I pulled over it stalled. It would start again but immediately stall. I had to have it towed home at a cost of $100 (thank God for CAA). My mechanic came over (Nice guy!) and checked everything out. He suspected an electrical problem because they can occur on this model but everything checked out. However, the fuel pump would not come on and there was no fuel in the line. I have to have the pump replaced at $300 for the part plus labor, which of course includes draining the gas tank.

The car stalled on me, in the middle of the busiest intersection in Victoria. Worst experience by far.

Sunfire XL 2.2L

  • Automatic transmission

I have a Pontiac Sunfire 2003. Last year it was 6 yrs old, about 90,000 km (56,000 mi) when my fuel pump died. Stopped at a shopping plaza, then couldn't start. Got it towed, on next day it was fine at the mechanic's. They said board computer did not record anything, so I got it back and did not repair anything. 2 weeks later it died on the road and we had to push it to an empty lot. This time the fuel pump was out. Replaced it and so far seems OK, but is intermittent and turns off when idling sometimes. Board computer doesn't record anything now either. It could be poor electric contacts somewhere, who knows?
