Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the negative battery terminal for safety.

2. Access the Fuel Pump

Lift the rear seat cushion to access the fuel pump access panel (located underneath the cushion).
Remove the bolts securing the access panel using a socket set.
Carefully lift the access panel to expose the fuel pump assembly.

3. Inspect Electrical Connections

Check the electrical connector to the fuel pump for corrosion or loose connections.
Clean any corrosion with electrical contact cleaner and reconnect.

4. Testing Fuel Pump Operation

Reconnect the negative battery terminal.
Turn the ignition to the "ON" position and listen for the fuel pump operation.
If the pump is silent, further testing is needed.

5. Measure Fuel Pressure

Attach a fuel pressure gauge to the fuel rail service port.
Turn the ignition to the "ON" position without starting the engine and observe the pressure reading.
- Expected pressure for the Camry: approximately 40-50 psi.
If pressure is low or absent, the fuel pump may need replacement.

6. Reassemble Components

If the fuel pump is functioning, reassemble the access panel and secure it.
Reinstall the rear seat cushion.
If the pump is faulty, proceed with the replacement steps.
