[QUOTE="Tiha, post: 1563514, member: 33189"] It hard to diagnose over the internet. Whether it be terminology, or understanding, or just not looking at the same things everyone else does. Just like in this case. I can find one person that explained conditions that matched mine. Everything else I find they all have metal shavings. Mine is clean. It is such an emotional roller coaster. Going into this I thought I would end up needing a decontamination kit. Then farther into is, maybe a couple injectors. Then maybe just a LPFP and at the end couldn't find anything wrong. Now back to needing a CP4. After measuring fuel pressure. 62 psi by manual gauge and still not getting it to start I pulled the intake again, pulled the flow control valve again. It is clean, no metal shavings. The only thing that makes sense is the suction valve failure in the CP4. I should have gotten a picture of the fuel flowing out. Maybe I will before I tear it apart yet. I tried to pull the pressure regulator off the Left rail, got the fender well out. Tired to get the return line off to do a flow test. I couldn't get it. Got the regulator loose. But then found out you can screw it out of there without pulling the hold down for the injector right there, or pulling the fuel rail loose. So I left it. Threw everything in back of the pickup and pushed it outside. I am out of time. Guess I will put a CP4 in it. But now, which one? It's not like I will probably put another 100k on this truck. Not increasing hp or anything. There is $700 remans that it seems nobody admits to using. Then the New factory replacements for $1000, then all kinds of options claiming to be better.
