Sure, you need to ground the fuel sender wire to make sure the gauge and wiring is okay and that the fuel level sender has failed from inside the gas tank. The wire color is dark blue, and it is at the wiring harness near the fuel tank. If you ground this wire with the key on and it goes to full the fuel level sensor is bad, here is how to change it out in case you need it. Check out the images (below).
