The fuel gauge is bouncing erratically every time the vehicle is in park or neutral but in no other gear. It has been fine for years but suddenly started acting up. The truck receives regular maintenance, but the start of the problem did not coincide with any maintenance or any event. It just started happening.
Fuel gauge acting very erratic and vehicle will not start have noticed online that many GMC sierra owners of similar years have experienced same problems very expensive to repair.
Gas gauge on 2000 GMC k1500 pick up truck working erratic. Sometimes gauge goes to empty and then a check engine light goes on. I understand that a lot of people with these trucks are having the same problem. GMC needs to have a recall thanks.
