William, I understand your frustration however I think all of this has been covered before but here are the basic steps that should work: First Have someone watch the fuel guage and ground the wire that goes to the sender. The gauge should respond, if not you have a wire or gauge problem. Do not jumper it to ground and leave it jumpered while you check the fuel gauge the range of the fuel sender is approximately 10 ohms full, 70 - 73 ohms empty. I don't know if could hurt the gauge but there is a world of difference between 10 ohms and a short circuit. Second When you have the gauge responding when you ground the wire at the sender attach the wire back to the sender and ground the sender, if this works you are done, if it does not work check the sender with an ohm meter. Start with the one that is not in the tank, you can move the arm and watch the resistance change. Again, you should expect to see approximately 10 ohms to 70 ohms as you cycle the arm. Third If nothing works shorting the sender wire to ground it may be the wire to the gauge cluster, you can unplug the harness from the gauge cluster and locate the wire to the sender using the factory manual and do a test of the wire from end to end using an ohm meter. If the wire tests good your problem is in the instrument cluster. If the wire is open try running a temporary wire and see if it works. Last but not least As with all trouble shooting these are just the basic steps, your conditions may vary I could be totally off. However if the wire is ok from the gauge cluster to the sender you should be able with the assistance of a friend watch the ohm reading change at the gauge cluster connector while moving the sender arm. If all fails you can install an aftermarket fuel gauge using your stock sender. Autometer makes fuel gauges that work with our senders, I have one installed in my 64 Sport Fury. I am running all Autometer gauges. The Autometer gauge does not depend on the voltage regulator in your instrument cluster, it runs directly on 12 volts. If you are not up to speed using a multimeter and checking ohms and voltage find someone who can help. Never attempt to take ohm reading on a circuit that is energized. Just some thoughts, good luck with the car. If you have any specific questions contact me directly, I can give you my phone number. Dennis C.
