Re: Fuel Gauge
First, be sure the gauge is getting power and a ground. Then, disconnect the sender wire from the gauge, then turn on the ignition. The gauge should read empty. Then hook a jumper wire from the sender terminal on the gauge to ground. With the ignition on it should read full. If these tests show the gauge as okay, then test the sender wire with an ohmmeter by disconnecting it at the sender in the fuel tank and ohmming from that end to the gauge end. You should get good continuity. Then while one end of the ohmmeter is connested to the sender wire -either end- connect the other connector of the ohmmeter to ground. There should be no continuity. If all these tests are okay, the problem is either a sender or a bad tank ground. Hook the jumper wire to one of the screws holding the sender in the tank and the other end to ground. If the gauge still does not work, The sender is bad. You can get a universal sender from NAPA, although you may need a gauge with it as some gauges are not accurate with some senders. It's not a big deal to adapt the sender to work in the tank, you will need to know the tank depth before ordering.
