OK UPDATE
I just checked the FPR and it checked out fine. I hooked up a mighty vac to the fpr and it held vacuum so it's good. The high pitched noise I have been hearing is just the air pump turning on, so I think that it's just coincidental that I sometimes get fuel pressure when I hear the air pump turn on. Even when it gets to the fuel ~43 psi in the run position(motor off), the pressure leaks down in a matter of 2 seconds tops. This is all pointing to a bad injector I believe in less someone else has any other insite?
