I have the dreaded fuel gauge issue. Been reading up on some of the other threads for tips to troubleshoot it but can’t seem to get anywhere. Issue is my fuel gauge reads empty all the time, even after I fill it up. I disconnected the sender at the rear bumper and the gauge pegged all the way past full. Reconnected it and it went back to empty. Tried to ground out the wire back to the gauge to see if it would swing the other way, but no luck. There seems to be a fuel pump and a bunch of connections ands hot wire kit installed. this is my first go around with the electrical on the gn, so go easy on the new guy. Appreciate any help I can get.
