If your Lexus RX is experiencing issues such as difficulty starting, engine stalling, or decreased fuel efficiency, a faulty fuel pump module might be the cause. Replacing this component can restore your vehicle’s performance and ensure safe driving. This guide provides step-by-step instructions to help you replace the fuel pump module in your Lexus RX safely and effectively.
Tools and Materials Needed

Preparation Steps
Before beginning, ensure your vehicle is parked on a level surface and the engine is cool. Disconnect the negative terminal of the battery to prevent electrical sparks. Relieve the fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Removing the Old Fuel Pump Module
Locate the fuel tank access panel, usually inside the trunk or cargo area. Remove the panel to access the top of the fuel tank. Disconnect the electrical connector and fuel lines from the old pump module carefully using the appropriate tools. Support the fuel pump and remove it from the tank, taking care to prevent fuel spills.
Installing the New Fuel Pump Module
Compare the new pump with the old one to ensure compatibility. Carefully install the new fuel pump module into the tank, reconnecting the electrical connector and fuel lines securely. Double-check all connections to prevent leaks.
Final Steps and Testing
Replace the access panel and secure it properly. Reconnect the negative terminal of the battery. Turn the ignition to the “On” position without starting the engine to prime the fuel system. Check for leaks around the fuel pump area. Start the engine and observe its operation, ensuring it runs smoothly.
