Solution

1. Preparation

Tools Required: Fuel pressure gauge, safety goggles, gloves, rags.
Ensure the vehicle is parked on a level surface and the engine is cool.
Wear safety goggles and gloves for protection against fuel splashes.

2. Locate and Access Fuel Pressure Test Port

Open the hood and locate the fuel rail on the engine.
Find the fuel pressure test port, which resembles a valve stem.
Remove any protective cap from the test port.

3. Connect Fuel Pressure Gauge

Attach the fuel pressure gauge to the test port securely, ensuring there are no leaks.
Make sure the gauge is positioned where it can be easily read.

4. Test Fuel Pressure

Reinstall the fuel pump relay to power the fuel system.
Turn the ignition key to the "ON" position without starting the engine.
Observe the pressure reading on the fuel pressure gauge. The expected pressure for a Toyota Camry in this generation should be around 40-50 psi (pounds per square inch).

5. Disconnect and Clean Up

Turn off the ignition and remove the fuel pump relay again.
Carefully disconnect the fuel pressure gauge from the test port.
Replace the protective cap on the test port.
Clean up any spilled fuel with rags and dispose of them properly.
