Hello! Welcome to the site! Thanks for coming! I'm Ron Z. I'm here to provide as much info and insight as I can, to best answer your question.

If you have a code for the Fuel Tank Pressure sensor and the Fuel Gauge is not working at the same time, the problem is going to be in the wiring going to the top of the fuel tank. The Fuel Tank Pressure sensor is mounted to the top of the fuel pump assembly located at the top of the fuel tank. The wire harness for the fuel level sensor, which is mounted to the side of the fuel pump assembly located inside the fuel tank is located here as well. I would suggest carefully inspecting the wire harness to the top of the tank looking for any loose, broken or rubbed through wires. Wiggle the wires around and see if the fuel gauge responds. If so, you'll need to find the short in the harness. Both of these are directly related, so it has to be in that wiring somewhere. Follow the harness as far as you can and inspect carefully.

It's got to be in that harness somewhere. Take your time and inspect it carefully. Let me know how you make out!
