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.

Since purchasing my truck, there has been an ongoing problem with it simply shutting down mid motion, causing brake and steering failure. Three months after purchase this problem was directly responsible for an accident (on an icy roadway) in nh. I have taken the truck to countless garages in an attempt to remedy the problem, to no avail. I continue hearing from several mechanics; "fuel injection problem - a bad year for gmc ..." the problem was only occasional at the start, and tolerable, but has gotten progressively worse - to the point where I no longer am comfortable taking it out of the yard - yet I continue paying off a loan for a truck I cannot trust. Again, I have dealt with three different garages (diesel), with competent mechanics, and after having various parts replaced - eventually find myself with the same problem occurring, again and again.
