Fuel Guage don't work

Either the fuel level sensor, fuel gauge or the wiring/connectors are malfunctioning, hard to say without a diagnosis. The first thing I would do is add a bottle of Chevron Techron Concentrate Plus to the fuel tank and drive it. I have fixed several erratic fuel gauge issues with this stuff. It cleans the fuel level sensor in the tank, give it a shot, it's a very inexpensive repair and it will also help to clean the injectors and valves as well. http://bit.ly/Techron_Concentrate

There are ECM issues with this problem. There is a technical service bulletin # 08-06-04-010 that refers to this. Sometimes the ECM can be re-flashed to correct this. A proper diagnosis will have to be preformed to determine this for sure. If you need more help, http://www.jaysauto.net
