OK its been far too long since I was a tech. But I still try to fix my own car problems. My 2007 Chevy 6.6 is in pristine condition with 171 K miles. I woke up a few days ago to find my fuel gauge totally inoperative. The low fuel light is on and I know it has at least 3/4 tank. I verified this by topping it off already. So I’m not sure where to start on diagnosing where the problem lies. Should I start at the tank harness or at the cluster? Thanks for any help….
