While driving the vehicle, the engine died. When taken to the dealership we were told the fuel pump had burnt up and the wiring boot had also burnt up. The technician implied that we were lucky that there had not been a fire. This is the second time that a fuel pump has failed in three years.

As fuel pump began to fail (intermittent starting problems), it caused wires going to fuel pump (wires are inside the gas tank) to overheat. The fuel pump connector was completely melted, and three inches of insulation on each wire was burned off. Bare wires could spark and ignite fuel vapors.

I contacted the federal safety agency several years ago and I was informed that gm had a large problem with the seat rails in their various vehicles. I understand that the federal safety agency has many-many vehicles to inspect. I have been fighting my gm dealer for the last 4 years with various problems-broken interior dor handle-failure(s) with the fuel injectors-fuel pump failures-burned wiring harnass(where I had to show them where the wiring harness was located-trained techs??-alternator failure-AC compressor failure-atc... The biggest problem of course is the seat rails. They could have been redisned and the metal should have been heat treated, the seat rails have a poor quality metal-heat treatment would have splved their problem{s}. I have taught auto repair for 30+ years and I have never dealt with such a bunch of non-caring ass holes. Made in america-purhaps I should purchase something from japan-at least they treat their customers correctly-driving a vehicle with loose seats makes me feel like im driving a found on the road dead car-ford (pinto). . I hope that the federal safety agency will take action on gm and stick it to them. Thanks for listening.

Hello, purchased vehicle new 7/96, in 9/96 in conversation with a fleet mechanic since fuel pump is located in gas tank I was advised to not go below 3/4 tank of fuel to prevent fuel pump failuer any thing lower than 3/4 will not keep pump cool and lead to failure I followed the advise. Failure #1 occured in 1997 "original pump" dont remember exact date but dealer repaired. Failure # 2 (of the pump that replaced the first one), occurd mar. Or may 1999 dealer replaced. Both failures resulted in total shut down. #1 occured while parked and #2 occured while driving in the city. Related issue: in june 1999 fuel filter replaced after failure. In july 99 while driving in california at hi way speeds and heavy traffic truck would temporarily shut down (no fuel no power) 6 times in a 100 mile span, resembled fuel pump again however it no longer acted up after parking for 24hours. I am scheduled to take vehicle in for search of problem next week. Excellent dealer service for repairs , and good truck, but am concearned with the fuel delivery system seems to be typical problem (fuel pump failure) with other gmc and chevy truck owners I was fortunate not to get into an accident but the potential is there, ie congested traffic etc.
