Solution

1. Preparation

Tools Required: Socket set, torque wrench, fuel line removal tool, OBD-II scanner, fuel pressure gauge, safety glasses, gloves.
Disconnect the negative battery terminal to prevent electrical shocks.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Access the Fuel Pump

Lift the rear seat cushion to expose the fuel pump access panel.
Remove the access panel by unscrewing the screws and disconnecting any electrical connectors attached to it.

3. Remove the Fuel Pump Module

Disconnect the fuel lines from the fuel pump assembly using the fuel line removal tool.
Disconnect the electrical connector from the fuel pump module.
Unscrew the retaining ring securing the fuel pump module to the fuel tank (use a hammer and a punch if it’s stuck).
Carefully lift the fuel pump module out of the tank, taking care not to damage the fuel sender unit.

4. Install the New Fuel Pump

Replace the old fuel pump with a new one, ensuring the new fuel pump is compatible with the Honda Accord model.
Attach the new pump to the fuel pump module and secure it with the retaining ring.
Reconnect the electrical connector and fuel lines to the new pump.

5. Reassemble and Test

Reinstall the access panel and secure it with screws.
Reconnect the negative battery terminal.
Turn the ignition to the "ON" position without starting the engine to prime the fuel system and check for leaks.
Start the engine and ensure proper operation.
