As on some cars, the fuel pump can be heard operating. I haven't had my Porsche long enough to know if you can on these cars.
Have you tried by-passing the fuel pump relay so that it is on all the time (for testing purposes)?
Next, take a fuel pressure reading. On the 993 there is a test port on the driver's side fuel rail; you might have an identical port on your model. You'll need a new cap.
Are the injectors getting a signal?
