Who ever thought of putting an electric fuel pump inside a tank of gas........
Check your other gauges for accuracy. They do that when a ground is loose.
Check the wiring from the fuel tank along the longitudinal frame for frays and shorts. Plugs are secured.
Under the hood, passenger side, check the fuel pump relay. Switch it with one of the others to test it.
Bring the vehicle to an auto parts store. Ask them to break out he code reader. Check for diag codes

If it was originally scanned by auto zone and they said Throttle Position Sensor (TPS),i would go back and have it scanned again,this will tell you for certain what it is.Try and get the code number and definition written down.If it were TPS again,the sensor itself would need to be replaced unless the cost was prohibitive,or the wires to and from the sensor and PCM (vehicle computer),ohms checked for continuity first.Eliminating the wires leaves 2 entities in the circuit,the PCM or the TPS.Checking circuits is costly in labor dollars.Good luck.
