Check the fuel pump fuse and relay. p0463 fuel level sensor circuit. p2068 fuel level sensor b. Could also be a wiring harness issue. Check for power at the fuel pump. While turning the key on, check voltage at fuel pump connector. Should have about 12 volts volts for 5 seconds at the fuel pump.

Where are the censor circuits located at
Expert:  Dan replied 10 months ago.

the fuel level sensor circuits are in the same harness as the fuel pump. the fuel level sensor is built onto the fuel pump. Check the fuel pump connector and make sure there is no corrosion, make sure it is fully plugged in.

You need to start with the basics. Check fuel pressure at the rail. Check for spark. Check for injector pulse. Check compression. Figure out which of these you do not have and go from there.
