What is your question?
Fuel guage jumps to empty to full. When problems first started: When full, it will register right; when under half tank it will shoot to full. When under quarter tank it would register as empty. Now its all over.

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
