Six problems related to fuel pump have been reported for the 1997 Chevrolet 1500. The most recently reported issues are listed below.
Truck was running fine with no indication of trouble when parked, upon reentry truck did not even attempt to start, engine would turn spin freely. Towed to shop. Fuel pump supposedly failed according to independent repair shop and was replaced with 46,000 miles on truck. Truck drove less than 500 miles and failed to start with seemingly the same problem. Towed to cheverolet dealership for repairs. Fuel pump sending unit connection inside the tank was burned out. Service manager said this was a common failure for all cheverolet trucks with vortec engines. He returned the defective sending unit to me and I could plainly see the burned electrical connection at the top of the unit. Under the right conditions an explosion would be possible if sufficient oxygen was in the tank. Fuel pump and component parts should last longer than 46,000 miles.
On 7/9/02 the truck would not start. Had it towed to the shop. It was found that the wires that attatch to the fuel pump, which is inside the gas tank, were shorted out. There is visible melting and corroding of the connectors. Considering that the whole device, plus the wiring is inside the fuel tank, and since there was a short in the wiring, there could have been a serious fire or explosion. This truck was a bomb waiting to blow up. Upon searching the internet, I have found many, many complaints regarding the gm fuel pumps failing and the wiring shorting out. No one has had any luck getting gm to recall the pumps, and since we just spent almost $500 for the repair, I thought I would inform you of this serious risk of injury. Gm should be concerned with this flaw, and I was told that they are aware of the problem.
