This is the second time instead of fuel gauge reading full it is reading low miles seems like gas needle went wrong way
why is gauge saying low fuel and I just filled it up? on 2006 Chevrolet Uplander
There could be a problem with the fuel sending unit in the tank, a problem with the gauge itself, or a problem with the wiring that sends the information. Typically the lower the gauge, the less resistance is present from the sending unit. Have the unit checked.
