It could be the gauge, the wires, a fuse, the sensor in the tank …

Most likely it is the sender (sensor) in the tank. It may be part of the fuel pump.

Check the fuse for the fuel level sender. Using your digital multimeter, check the fuse socket for power with the ignition switch in RUN. If the fuse is good, and there is 12 volts dc in the socket, go to the electrical connector at the gas tank. Check for 12 volts on the wires which are not black with a white stripe, or, plain black (these two go to the fuel pump). If there is 12 volts, check the resistance of the wires going into the gas tank fuel level sensor. If the ohm value is more than a couple hundred, there is a problem with the fuel level sensor.

The problem is usually caused by a defective gas tank sending unit or a corroded sending unit wire connector.

I think the unit is accessible on this car by removing the rear seat cushion.
Disconnect the sending unit, and with the key in the RUN position, run a jumper wire from ground to the yellow/white (memory is fuzzy here?) wire in the wire connector plug.
If the gauge needle starts up and shows a FULL tank in a few seconds then you know the tank sender is bad.

If you’re at the point where the sender is bad then this is the best time to replace the entire assembly; fuel pump, filter, and all.

Hope that helps.
