After the basics of checking fuses grounds and instrument cluster connections, determine the resistance range of the sender unit and wire up a potentiometer with the same range and attach it to the connector after removing it from the sender. Then turn the potentiometer and see if the fuel gauge behaves as expected.

Be careful to see that there are no fuel vapors in the area where you are hooking up the potentiometer. Make sure you use the center post and an outer post on the pot so that you will get varying resistance.

Good luck,
