the fuel pressure regulator is located at the end of the fuel rail with the fuel injectors.it will have a vacuum line attached to it.if you want to check it install a fuel pressure gauge see what the pressure is at running(53-59psi) unplug the vacuum line and if it is working the pressure should increase 3-5 psi. that means its working.or test it with a vacuum pump,apply 12-14 in of vacuum,should hold vacuum.post back with any other questions.
