    Fuel Gage acting erratic.

    About a week ago my fuel gauge began dancing around while driving. Here is what has been tested.

    • Sender is good. tested fine in another car.
    • Fuel gauge tested from other cluster. Same results.
    • System grounds G200 and G300 tight
    • Orange low fuel light works
    • When you wiggle the sender while its loose on the fuel pump bracket the needle dances. When its bolted tight onto the bracket it gives a reading that is not correct.

    Any ideas welcome.

      Forgot about that left sensor. Pulled the sensor. Got OL with no change in resistance as bob moved up and down. Pulled the cover and found the problem. Thanks
