No voltage at gas gauge
OK I found the problem. I took a volt reading at the gas gauge with the key turned on and did not get any voltage. The wire that feeds the gauge comes from a switched terminal on the fuse panel. I checked the fuse panel and got a reading so I knew then the wire was bad. I fished the wire out of a spegetti network of wireing and discovered a rodent had chewed the wire in two. I installed a new wire from the fuse panel to the gauge and it works great now. Thanks to all who responded.
