I have a 2003 GMC Envoy and my gas gauge has been flowing up and down to empty and full recently it has stayed on empty. How do I fix it?


Ensure that all of the wire connections are clean, secure and corrosion-free.

  • 2 Check your fuel gauge fuse if the gauge's indicator stays on empty when your turn on the ignition. If the fuse is good, join the sending unit connector to ground. Replace the sending unit if the gauge indictor moves to the full line.
  • 3 Ground the terminal located on the back of the fuel gauge with a jumper wire if the indicator doesn't move. If it does move, consider replacing the wire between the fuel gauge and the sending unit. A poor ground is frequently responsible for fuel gauge problems.
  • 4 Release the wire that connects to the fuel tank's sending unit. Confirm that there's no worn insulation that would permit wire contact to the body or frame. A fuel gauge reading of full generally indicates a problem with the tank unit, not the wiring.

    Fuel gauge doesn't work on a 1989 dodge omni


    Hi

    Sounds like he forgot to reconnect the wires ?

    Check this first, if they are OK, bridge them, and the fuel gage should read full.
    If this is so, you can get a new tank unit.

    Expect he has left the wires off !

    Good Luck !

    a FixYa rating would be appreciated Please !
