Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the fuel system.

Tools Required:

OBD-II scanner
Multimeter
Fuel pressure gauge
Socket set
Screwdrivers

2. Replace Fuel Pump Relay

Remove the fuel pump relay from the fuse box.
Test the relay with a multimeter. If defective, replace with a new relay.
Reinstall the relay and reconnect the battery.

3. Replace Fuel Pump Fuse

Locate the fuse box and remove the fuel pump fuse.
Inspect the fuse for continuity using a multimeter.
If blown, replace with a new fuse of the same amperage rating.
Reinstall the fuse and reconnect the battery.

4. Replace Fuel Pump

Relieve fuel system pressure by removing the fuel filler cap.
Disconnect the negative battery terminal.
Remove the rear seat cushion to access the fuel pump access panel.
Remove the access panel screws and lift the panel.
Disconnect the electrical connector from the fuel pump.
Disconnect the fuel lines from the pump.
Unscrew the retaining ring and carefully lift out the fuel pump assembly.
Install the new fuel pump by reversing the removal steps.
Ensure all connections are secure and reinstall the access panel.

5. Check Fuel Pressure

Attach a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position to check the pressure reading.
Ensure it meets manufacturer specifications (typically 40-50 psi for Honda Accord).
If pressure is low, further diagnosis or replacement may be required.
