Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal to ensure safety.

2. Access the Fuel Pump

Remove the rear seat cushion by pulling up on the front edge to release the clips.
Remove the access panel covering the fuel pump. This may require a screwdriver or socket set.

3. Test the Fuel Pump

Connect a fuel pressure gauge to the fuel rail's Schrader valve.
Turn the ignition key to the "ON" position (do not start) and check the fuel pressure reading. It should be within the manufacturer’s specified range (typically 35-50 psi for the Camry).

4. Replace the Fuel Pump (if necessary)

If the pressure is low or the pump is not operating, disconnect the electrical connector from the fuel pump.
Remove the fuel lines carefully, using a line disconnect tool if needed.
Unscrew the retaining ring or bolts securing the fuel pump assembly and lift it out of the tank.
Install the new fuel pump by reversing the removal steps and ensuring proper sealing.

5. Reassemble and Test

Reinstall the access panel and rear seat cushion.
Reconnect the negative battery terminal.
Start the engine to verify successful installation and check for leaks.
