A: Check the battery, fuel filter, fuel line, hoses, and quick-connect fittings. Have an assistant turn the ignition switch to ON to verify the fuel pump is running. Relieve the fuel system pressure and connect a fuel pressure gauge to the test port on the fuel rail. Check for leaks in the fuel line, hoses, connectors, and fuel injectors. Inspect the fuel strainer and consider replacing the fuel pump module. Check the fuel pump fuse and relay.
Q: How to Remove and Install the Fuel Pump/Fuel Level Sending Unit?
A: Depress the connector tab and remove the fuel pump/Fuel Level Sensor electrical connector. Use a terminal remover tool to remove the terminals. Depress the tab and slide the Fuel Level Sensor out. Place the electrical leads in the groove and slide it up until it snaps into place. Push the Sensor wires up until they lock into place. Install the locking wedge and push the connector back up. Finally, install the fuel pump/Fuel Level Sensor assembly.
Q: How to Replace the Fuel Pump/Fuel Level Sending Unit Module?
A: To begin, relieve the system fuel pressure. Before removing the fuel pump/fuel level sending unit module, make an alignment mark on top of the Fuel Tank to ensure correct realignment during installation. Loosen the fuel pump/fuel level sending unit locknut with a pair of large water pump pliers. Remove the fuel tank carefully, ensuring not to damage the fuel pump inlet strainer or bend the sending unit float arm. If replacing either the fuel pump or the fuel level sending unit, separate the two components. Inspect the pump inlet strainer while the pump is removed, ensuring it is not clogged or damaged. If dirty, wash it in clean solvent or replace it if still clogged. Finally, during installation, tighten the fuel pump/fuel level sending unit locknut securely.
