December 18, 2011What are the symptoms of a fuel pump that is going bad? Does it give problems or does just go bad all at one time?

December 18, 2011When mine went bad earlier this year I had symptoms. There were a couple of times the truck wouldn`t start and you couldn`t hear the fuel pump working. eventually it would turn on and run fine. then later it would stop when i was driving. After being stuck on the side of the road i got around to fixing it haha
December 19, 2011Mine whined for about six months before it croaked. High-pitched whine. It was especially noticeable on long drives when I`d run the tank pretty low to empty. No other symptoms.
Fortunately, it died right near my house. Unfortuntately, being a Suburban, and not being able to lift off a bed to get to it, it cost me $700 for the repair.
Keep the tank at least half-full, especially during the hotter months. Helps keep the pump cool.
September 10, 2012On my 98 when the pump was going out you could hear it whine. When I would try to give it too much acceleration on take off it would scream like I was going 100 mph but act like it wouldn`t shift out of first gear. Under normal take off- you wouldn`t know anything was going bad. Best way to change it is lift the bed up or off because the lines going into the pump are plastic and if you drop the tank you will more than likely break them off. This is how the dealer does it.
