To begin the process, relieve the system fuel pressure and equalize tank pressure by removing the fuel filler cap. Next, disconnect the cable from the negative battery terminal. Then, remove the fuel tank. After that, disconnect the fuel supply and return lines from the fuel pump/Fuel Level Sensor, using a shop rag to soak up any spilled fuel. Mark the orientation of the fuel pump in relation to the fuel tank to ensure correct realignment when reinstalling. Using a pair of large water pump pliers, unscrew the fuel pump/Fuel Level Sensor locknut. If the locknut is tight, carefully tap it loose with a hammer and a brass punch. Carefully remove the fuel pump/Fuel Level Sensor from the fuel tank, taking care not to damage the fuel inlet strainer or the fuel level sensor float arm and float. Before installing the pump, inspect the O-ring for cracks, tears, and deterioration, and replace if necessary. Also, inspect the fuel pump inlet strainer and clean it if dirty. Installation is the reverse of removal, making sure not to damage the fuel inlet strainer, float arm, or float. Finally, when the battery has been disconnected, the Powertrain Control Module (PCM) must relearn its former driveability and performance characteristics.

If the fuel pump does not come on, the fuel pump fuse, relay, and wiring should be checked.

If the fuel pressure regulator is okay, the fuel pump module or fuel injectors may be clogged or defective.

Disconnect the positive and ground wires from the top of the fuel pump.

Disengage the locking tab to detach the connector housing from the bottom of the fuel pump cover.
