Well...finally got fuel gauge to work but backwards...have completed every test on this site that has been addressed. In the last trial i took everything out of truck..gauge and sender...worked fine. I put the gauge cluster back in truck and manually moved sender up and down and it worked!! Put sender back in tank and read half full which was correct. After patting myself on the back I turned the key off and gauge went to full!!!! Turned key off and the gauge never moved. Pulled sender back out. Key on, all worked fine...sender back in tank ...read half full...turned key off and gauge moved to full and won’t come back. Tank is grounded, cluster is grounded, gauge is grounded.. can remove sending wire with key on and gauge will show past full as it should..put wire back on and it goes to full and stays there whether key on or off...checked the key switch and all good. As stated several times before ...will work fine on bench test but not in truck. I’m giving up and going to start work on my bed wood...if anyone can think of anything I might try or tast let me know...time for Super Bowl ! Go Chiefs!
