Re: Gas Guage problem
You don't go replacing/guessing until you properly do the troubleshooting.
Basics of basics.
Unplug the TAN wire connection that links the gas tank sending unit to the rear lighting harness in the trunk.
The tan wire "half" that leads into the trunk----touch it to good ground with the key on, fuel gauge should go to EMPTY.
Leave the tan wires disconnected, with the key on, the fuel gauge should go past full. If these conditions are satisfactory, the gauge and wiring leading to rear of vehicle are OK.
Post back if you need more help/next steps to try.
