1999 GMC Suburban: fuel pump failure

Filed Jun 7, 2022 · Fuel system · IA

The original fuel tank in this vehicle way rusty and leaking. I replaced the original tank with a Dorman model 576-372 fuel tank. This tank included a new fuel pump lock ring, which was used to secure a new fuel pump in the tank prior to installation in the vehicle. The lock rung failed approximately one week after installation allowing the fuel pump to raise up out of the tank. At the next fuel up a large volume of gasoline escaped form the fuel pump opening and spilled. The defective lock ring was replaced with a OEM part and was subsequently discarded.

Fuel pump/connector failure. Initially engine would shut down intermittently. On last occasion, vehicle engine shut down resulting in loss of power steering, power brakes, etc. Would not restart. Former gm mechanic told me that he witnessed this problem numerous times and found most cases involved failure of electrical connector or ground connection at fuel pump.

Dt: the consumer stated that while driving with a quarter tank of gas the vehicle stalled without any previous warning. Then, it completely died. The consumer pushed the vehicle to the side of the road. The consumer was finally able to restart the vehicle after several attempts, and drive home. The next day he inspected the connection to the fuel pump. He discovered there was low voltage to the electrical assembly area. The federal safety agency recall campaign 05v155000 was issued involving the same type of vehicle. This vehicle was not included in the recall due to the VIN, but was experiencing the same problem as indicated in the recall. The consumer called gm ,who suggested a diagnostic test. No repairs have been made due to the expense of the repairs. *ak (11/22/05) *sc updated 01/10/07.

Vehicle engine will intermittently stall or cut out at highway speeds. This condition occurs approximately once or twice a month under varied driving conditions. The vehicle will restart immediately after stalling. Several times when this has occurred, the service engine light will come on, but it will turn off after 20-30 miles of driving. This has been occurring for over a year now, I have taken the vehicle to three gm dealerships, and they claim they cannot replicate the problem. They have replaced the fuel pump at my expense, and the catalytic converter under warranty. I have also taken the vehicle to two independent shops for the same problem and they have also not been able to replicate the problem or offer a solution, other than replacing the basic components (spark plugs , plug wires, fule filter etc), which I have had done.. This is an extremely dangerous problem, primarily because when the engine stalls, the power brakes and steering also fail. I live in a mountainous region of virginia and have had this happen while driving mountain switchbacks. This vehicle weighs almost six thousand pounds, and a loss of power brakes and steering while descending steep mountain grades with sharp curves creates an extremely dangerous and life threatening situation. Thank you for your assistance.

Fuel pump has been replaced two times due to loud noises. Also, transmission was replaced because it did not shift gears automatically, rough switch. Abs brakes did not operate properly, causing extended stopping distance. In addition, two tires replaced in the rear due to vibration of vehicle. Dealer contacted, and are attempting to remedy the problems that exist. Provide further information.
