The most recent problem started last week, my wife moved the car in the morning and in the afternoon it would not start after several attempts. I came home early from work and it started right up. A few days later same problem, this time no easy fix. I have disconnected the battery, to reset the computer, checked all wires, checked spark (OK), the only thing is seems not do is deliver fuel. I replaced the fuel filter, for the 3rd time in 4 years, but the fuel pump will just not run. It usually runs for 2 seconds when turning the key to the run position before starting, but no more. I has always been a noisy pump in the entire 4 years we have owned the car, and yes we bought it used.
Yesterday I replaced the fuel pump relay, but to no avail. I cannot find a fuse for the fuel pump and all other fuses were checked and are good.
The dealer has quoted me almost $900 to replace the fuel pump, with a lifetime warranty on the part and labor, so I am tempted to take them up on it - but there is no guarantee the problem IS the fuel pump; they will scan it and let me know. Without dropping the tank I really have no way to troubleshoot or inspect the fuel pump or wire harness, but the fuel guage does work so I am assuming that the wiring is good based on that.
Other than the obvious advise (let the dealer fix it or not) what fuel pump does my Tahoe take (RFI filter pump or not, with or without Low Lubricity Fuel System Sender, with or without Robust Fuel System Sender, etc) and if there is a fuse for the fuel pump, where is it? VIN number available on request.
have the same problem?
