Solution

1. Preparation

Gather tools and safety equipment.
Tools Required: OBD-II scanner, multimeter, fuel pressure gauge, socket set, screwdrivers, safety goggles, gloves.
Safety Warning: Disconnect the battery before working on the electrical systems.

2. Access the Fuel Pump

Remove the rear seat: Unclip or unbolt the seat to access the fuel pump access panel.
Remove the access panel: Unscrew the panel covering the fuel pump.

3. Test the Fuel Pump

Check electrical connectors: Inspect the connectors for corrosion or damage; clean or replace if necessary.
Connect the fuel pressure gauge: Attach the gauge to the fuel rail service port.
Turn the ignition ON (do not start the engine) to check fuel pressure. It should be within the specified range (typically 30-50 psi for the Camry).
If pressure is low, it may indicate a failing fuel pump.

4. Replace the Fuel Pump (if necessary)

Relieve fuel system pressure: Depress the Schrader valve on the fuel rail.
Disconnect the fuel lines: Use appropriate tools to safely disconnect the lines, capturing any residual fuel in a container.
Unbolt the fuel pump assembly: Carefully remove the pump from the tank.
Replace the pump: Install the new fuel pump, ensuring all seals and gaskets are in place.
Reconnect the fuel lines and electrical connectors.

5. Reassemble and Test

Reinstall the access panel and rear seat.
Reconnect the battery.
Start the engine and check for proper operation and leaks.
