So, you're not getting any HiPres Oil and that's certainly what's keeping you from starting. I'm not sure if a Totally Open IPR would have you getting only 30psi, maybe with Air in there, I mean it's not going to purge without pressure to drive it out through the Injectors...

But let's start with the IPR, maybe put a constant 12v into the coil (from the battery) and see what that does. Did you by any chance keep the old one? Throw that in if you did (and these are Motorcraft sensors? Not Aftermarket ~ right?)

From there you're gonna need a Gauge and the ability to block-off each side to be able to find why it's so low (which means either the pump isn't able to make good pressure, or the good pressure it is making gets bled-off somewhere).

God Vid ->
