The regulator will be on the return fuel line near the manifold. Just follow the fuel rail which sits above the fuel injectors and figure out which way is in and trace it around and you will see a part with a vacuum line attached to it and it willl be attached to the fuel rail. This is the return line and that is the pressure regulator.
If your pump is turning, I would go ahead and check the fuel pressure next.
Advance Auto ro Auto zone loan out test tools for testing fuel pressure. You will see a valve on the fuel rail which is where you will take reading from. There will be adapters in kit. Make sure car sits for a while so fuel pressure drops and still cover with rag whenever opening fuel system in case there is risidual pressure.
