    Gas guage not working replaced sending unit already and nothing. It’s buried below the E mark. E is at about 8 o’clock and needle is at about 6 o’clock. If I move the needle up manually it just falls right back down. If I move it past full it falls to the opposite side just as far down.

    Brand: Chevrolet
    Model: Lumina

    I don’t know your knowledge, but the easiest way is to first measure the ohm to the sender near it, then measure it from the gauge connector. If it’s not the same ohm then it’s a wiring issue somewhere. To test the gauge you need an ohm tester and load it to see if it’s moving!
