MORE THAN LIKELY THE GAUGE HAS GONE BAD OR DISCONNECTED SOMEHOW. YOU CAN ALSO CHECK THE FUSES UNDER THE HOOD AND ALSO THE ONES INSIDE THE CAR. BUT ON MOST CARS, MOST OF THE THEM USE THE SAME FUSE FOR SEVERAL OTHER GAUGES SO SOME OF YOUR OTHER GAUGES WOULD NOT BE WORKING ALSO. CHECK FUSES BEFORE BUYING A NEW FUEL GAUGE. ALWAYS CHECK THE SIMPLE THINGS FIRST TO SAY TIME AND MONEY. ALSO DO RESEARCH ABOUT IT. YOU CAN FIND ALOT OF GOOD AUTO REPAIR SITES. I HOPE IT HELPS AND GOOD LUCK. JEAN
