How do you fix a fuel gauge on a 1993 Ranger pickup?

Answer 1

There should be a grey plug just under the master cylinder disconnect it and turn on the ignition if the gauge reads full the problem is the sending unit in the tank (thats if the gauge was reading empty before). You can also check the sending unit by using an ohm meter and checking for 22.5 ohms at empty and 145 ohms at full the wires are the yellow/white and black/yellow that are coming from the grey plug I was talking about earlier. If the sending unit does not read in limits you will need to drop the tank and replace the sending unit that is connected to the fuel pump in the tank.
