To remove the fuel pump module, start by relieving the fuel system pressure and disconnecting the cable from the negative battery terminal. Then, remove the fuel tank from the vehicle and disconnect the fuel lines and EVAP line from the fuel pump module. While prying the locking tab out, rotate the fuel pump module retaining ring counterclockwise until it's loose. Carefully remove the fuel pump module from the tank, making sure to angle the assembly slightly to avoid damaging the fuel level sending unit float. It's important to note that the electric fuel pump is not serviced separately, so in the event of failure, the complete assembly must be replaced. If necessary, transfer the fuel pressure sensor and fuel level sending unit to the new fuel pump module assembly. For installation, clean the fuel tank sealing surface and install a new seal on the fuel pump module. Align the fuel line fittings with the fuel lines and press the fuel pump module down until seated. Install the retaining ring, ensuring it is fully seated and the locking tab is engaged with the slot. Finally, complete the installation by reversing the steps of removal.

Check the fuel pump fuse and relay, and if they are good, diagnose the PCM.
