Q: How to Remove and Install the Fuel Pump/Fuel Level Sending Unit Module?
A: The fuel pump/fuel level sending unit module consists of the fuel filter/fuel pressure regulator, electric fuel pump assembly (including the fuel pump inlet filter), and fuel level sending unit. To remove and install the module, the entire assembly must be replaced as none of the components can be replaced individually. Start by relieving the fuel system pressure and disconnecting the cable from the negative battery terminal. Then, raise the vehicle and secure it on jackstands. Remove the fuel tank and clean the area around the fuel pump/fuel level sending unit to prevent dirt from entering the tank. Mark the position of the arrow on the fuel pump module for proper installation. Use pliers or a hammer and brass drift to loosen and unscrew the lock-ring, and carefully remove the fuel pump/fuel level sending unit module from the tank. Inspect the large rubber gasket sealing the mounting hole and replace if damaged. When installing the module, align the embossed arrow properly. The installation process is the reverse of removal.
Q: Where is the Fuel Pump Located and How Can it be Checked?
A: The fuel pump can be found in the fuel tank and can be checked by turning the ignition key ON. If the pump does not come on, check the fuses and wiring. If the pump runs consistently, the PCM or TIPM may be defective. To check, relieve the system pressure and connect a gauge to the injector Fuel Rail. Start the engine and check the pressure; if it is not within specifications, check for restrictions or replace the fuel pump module.
