Question Fuel Gauge doesn't move at all!!!

I have a 2002 Ford Explorer and the fuel gauge stays on empty all the time. Need tips on how to find out wether it is the float or the whole sending unit itself. Also would like help on how to fix problem if it is the float or the sending unit.

Thanks

There is no choice between the float and the sending unit. That is determined by how the dealer sells it. You won't have anything to say about it. What you have to determine is if it's the sending unit or the dash gauge.

Thumbs up

A low fuel gauge reading indicates low resistance in the circuit. First you need to find the electrical connector back near the fuel tank and unplug it. Now turn the ignition to the run position. If the gauge goes to full, the problem is in the sending unit, replace it. If it stays on empty you then need to take out the instrument cluster and with the sending unit still disconnected, check the sending unit wires (the vehicle harness not the unit) (feed wire YE/WH ground BK/LB) for being shorted together or the feed wire (YE/WH) for being shorted to ground. If the wires are ok, the instrument cluster is the problem, replace it.
