could be that your fpr is not seeing boost, and this is why it will not increase the fuel pressure. check your vacuum line. It will not increase pressure until it sees boost.

What typw of fpr is it? If it's the Cartech FMU...then get rid of it and buy a Vortech S-FMU.

If you do have the Cartech, try connecting the vacuum hose to the OTHER barb that's on the top. Swap the bleed valve and vacuum hoses and see what happens. I didn't know which was which at first and had the SAME problem. Try that and let us know!
