use the pressure test port on the top of the engine, it is on the fuel rail that supplies fuel to the injectors, looks like a tire valve, will have a plastic cap on it.

SOURCE: fuel pressure regulator
Two places to look...if you have separate injectors for each cylinder then regulator should be at the front end of the fuel rail. If you have throttle body injection it is on the throttle body itself.
