Hey guys I have a question for you. I own a 2000 GMC Jimmy and I've started experiencing problems with my gas gauge. When I initially start the vehicle is starts going back and forth from empty to full and once I put it in gear it still does the same thing. Sometimes it eventually stops around the half full marker but it starts jumping around again. I wasn't sure if it was the fuel tank sensor or it I have a short some where. I was curious if anyone else has had this problem and what they did to solve it. I'm just trying to see if I can avoid getting my a** handed to me by the dealership if i have to take it in.
