I removed the cluster from the dash and did my tests with a good ground. Also look at number two in my post above I removed the sender wire from the sender and it swept to full and I grounded the sender wire and it swept back to empty without contacting the glass of the cluster. The only thing here that has changed is the gas gauge. I sent it in for refurb of cluster and the gas gauge before sending it in was working. Just went out and jumped ground straight to the neg terminal on the battery and gauge still not reading the right fuel level.
