There should be a test port on the driver side fuel rail. Remove the cap and install a fuel pressure gauge(you can get on at any auto parts place. I am going through a similar problem right now but I have no pressure and I am almost 100%positive it is my fuel pump. I think if I remember correctly the book said your pressure should be about 35-45 psi, I will try to double check that if I can remember.
