Disconnect the wire at the sending unit and ground it with the key on. The dash gauge should go to full or empty, I never can remember witch, then un ground it and it should go to the opposite extreme. If that works then the sending unit is most likely bad but all the wiring and the gauge are good. Check the ground at the sending unit. Next remove the unit from the tank and hook the wires back up and with the key on move the float up and down and see if the gauge responds to the float movements. If not the tank unit is bad. If that all works the float might be saturated with gas and to heavy to float. Replace the float if you can find one or the whole sending unit. If the dash gauge does not respond to any of the above then you got a big problem trying to track down a bad wire or dash unit. Hope this helps.
Fuel gauge doesnt work.
Well Since my gf and I got her truck up and running about a week ago we are finding little bugs here and there. One of the things I need help on is the fuel gauge doesnt read anything.
The sending unit is new and she has somewhere around 1/2 tank but the gause reads empty.
We dont know if it ever worked tho thats the thing. we bought the truck and tore it apart the day we bought it.
How do I test if the gauge works?
