Four problems related to fuel pump have been reported for the 1996 GMC Sierra. The most recently reported issues are listed below.
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.
While driving fuel pump stopped pumping fuel,causing engine to stall out without any warning.
Fuel pump failed.
