As riddle said, how does the pressure hold after you turn the key off? Does it drop?
The FPR is off the back side of the injection spider under the plastic upper plenum. The SCFI motors don't have anywhere near the problems with the FPR that the CPI motors had.
One other way to lock it down to the pump would be to remove the fuel filter and hook up a pressure gauge on the supply line back there. This would eliminate the FPR from the equation. If your pump does not reach 60psi, then you either have a pump or a voltage supply problem...

I am still going with a pump issue but to make sure do the test Swartlkk suggested to make sure so your not just swapping out part after part!!!
