Disconnect the battery. Pull the carpet from under the left rear passenger door kick plate. Locate the conduit on the left side of the car and expose the Purple and Black/White wires in the wiring bundle that has the clear level ride line (ELC) in it. Strip back about 1/2 inch of insulation from each wire. Do not cut the wires. Solder one end of a 2000 ohm resistor to the purple wire and the other end to the black/white wire. A 1/4 or 1/2 watt 2000 ohm resistor is recommended, but the resistor can be from 1800 ohms to 2200 ohms. Tape the connections to prevent any electrical shorts.
By the way, "fantastic88" wrote that the sensor problem cause the fuel pump to fail.
Awesome tip! I'll have to try that when the weather gets nicer...and I have some spare time!
