Make sure you get fuel out of the bleeder screw on top of the filter housing, then if there are no other leaks or issues you should be able to crank until it fires up! It's usually under 30seconds

You should bot be cracking the injector lines open. Not like old school systems. It will start if everythibg is in correct working condition. Why did you change cp3's?

Do you have anything to monitor rail pressure? How long have you been cranking? What kind of lift pump? Did you delete the factory filter?

FPRV is going to be on your driver side, PPE has directions on installing their race fuel valve and that is pretty detailed. Here is the link for it.

If it is your FPRV, i don't believe that efi will tell you from what i understand of efi all it can tell you that would be related would be rail pressure and commanded rail pressure. Search "bottle test" and that will explain on how to check the FPRV.

Never crack a injector line open on a common rail diesel to bleed air out of the system. Its very dangerous do to high fuel pressures. Not like the old days.
