It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

  • Truck will be idle, low fuel light comes on. I can start the truck, and will have full tank of gas, will say low fuel

  • no matter how much fuel is in the tank the guage always shows empty, getting very frustrated

    The low fuel light and fuel guage both indicate no fuel, yet I may have just filled the tank. The light and guage make alternately go on and off at any time, moving or stopped and with any amount of fuel in the tank.

    The problem has not been repaired yet.

    As an example, I can go out and start my truck, and the fuel range indicator read "75 mile range" left to travel and the fuel gauge stating I have about an 1/8th of a tank of gas left. Go about two (2) miles down the road to the hardware store, go inside, come out and start the truck and the "low fuel warning" light will be on and the fuel gauge indicator will be buried on E. When this situation happens and I will stop and fill it up only to discover that it will only take between 15 to 21 gallons max. The window sticker and manual for this truck indicates it has a 26 gallon fuel tank. GM said this is normal to have variations in fuel ranges. Probably my last GM vehicle.

    Fuel guage inaccurate. Fuel guage reads empty but tank takes only 14 gallons.

    It will not read full when it is full , it has a tendency to go to empty which causes the empty fuel light to come on. I never fixed it.

    I bought the truck new in 2000,This problem with the fuel sensor occur right after I had the throttle body replaced in 2005, the service rep at the GMC dealer told me at that time it would cost in the neighborhood of $500 to repair I,ve always had a whistling sound coming from the gas tank since the truck was new, I have just put up with the imperfection since

    been through 3 fuel pumps and doing it again. sending unit only works when moving and on rough road. at 250.00 a piece you would think this would be a quality part but I guess gm makes all their money on parts sales.
