The 1992 Toyota Camry was either available with a 2.2L four-cylinder engine, or a 3.0L V6. The process of checking the car’s fuel pressure is the same in either model. The recommended fuel pressure for the 1992 Camry is between 38 and 44 psi (pounds per square inch). This is the same for both engines. The only way to test the fuel pressure is to use a fuel pressure gauge. If your fuel pressure is out of line, it could indicate a problem with your fuel pump or fuel regulator.

Test the Fuel Pressure
Turn off the 1992 Camry’s engine. Open the car’s hood and support it with the prop rod.
Inspect the back half (close to the windshield) of the engine compartment to find the fuel rail. On the four-cylinder model, the fuel rail is very close to the windshield. On the V6 model, the fuel rail is between the center of the engine compartment and the windshield. The fuel rail is a large pipe that runs horizontal across the back half of the engine. It runs along the intake manifold.
