Relieve the system fuel pressure. Disconnect the cable from the negative battery terminal. Remove the fuel tank. Clean the top of the fuel pump module. Disconnect the quick-connect fittings from the fuel pump module. Note the orientation of the pump mounting flange and mark the orientation of the fuel pump in relation to the fuel tank to ensure that the fuel pump is correctly realigned when you install it again. If you're going to install a new pump, note the location of your alignment mark on the old pump and make a mark at the same spot on the new unit. Using a pair of large water pump pliers, unscrew the fuel pump module lock ring by turning it counterclockwise. If the lock ring is tight or pliers will not work, use a hammer and a brass punch to loosen it. Remove the pump assembly, taking care not to damage the fuel level sensor float arm and float. Before installing the pump, inspect the O-ring for cracks, tears, and deterioration. If it isn't in perfect condition, replace it. The float arm may need to be installed onto the new fuel pump module. Note the installed position of the float arm on the old module and snap the float arm onto the new module in the same position. Insert the fuel pump/fuel level sensor module into the fuel tank, align the mark that you made on the fuel pump/fuel level sending unit flange with the mark you made on the tank, and carefully seat the pump flange on the tank. Make sure that you don't damage the float arm or the float during installation. If the float arm is bent, the fuel level that is indicated on the fuel level gauge on the instrument cluster will be incorrect. Remaining installation is reverse of removal.

First of all, to test the fuel pump, turn the ignition key to ON and listen for a whirring sound. If not heard, check the fuel pump fuse, relay, and wiring. If these are fine, the pump may be damaged. If the pump runs continuously, the PCM could be faulty.

The first step is to remove the engine covers.
