Rcimp & Mike , When you look at the back of your gauge cluster where the fuel gauge segment goes there are 3 holes. The 2 outer holes have your power lead, and the sender wire. The center hole will have access to the ground terminal. Take your ohm meter and check for continuity between the center hole and the cluster outer attachment lugs. This was where I had the most trouble. Ended up taking the segment out and sanding the inside of the cluster to get good ground contact. My troubles aren't over, but at least I got the gauge to read. Let us know what you find.
