New lml engine build, no fuel rail pressure
I'd double check you have the feed going to the correct port on the CP3- 2004LB7

If that is correct, you aren't building fuel pressure. It will never start with it that low- 2004LB7

On the last video, can't see which one os actual and which one is commanded fuel rail pressure. But if the lower one is actual then you aren't building pressure. Lost prime or lift pump isn't working if you have one And fist video, not sure but I'm not seeing much of a CAM signal or count- 2004LB7

If you got no injector signal. I'd verify your cam signal is good and in sync with the crank signal. The ECM won't fire the injectors without a CAM signal unless the engine is already running and it looses the CAM signal- 2004LB7

Lml piston install
Sounds pretty good to me. Only thing I can hear that may be off is a hiss like an exhaust or boost leak- 2004LB7

Placerville isn't that far from me. If you are interested, I can likely go take a look at it and do a pre inspection for you. I don't have Facebook so you'd have to contact the guy for me.- 2004LB7

Lml piston install
Sounds like it could be timing knock because it goes away with more boost. If you aren't running a tune or it's the same as before the piston change, then I'd be inclined to think you have more compression with the new pistons. Either via less clearance from the piston top to the head or better...- 2004LB7

In need of a little assistance.
As others have said. MAF value is way too low -
In need of a little assistance.
The two items I find most often for lack of power when it's obviously not in limp mode is lack of air or fuel. Air could be MAF and check fuel pressure vs actual Log both of those and report -

That's pretty cool. We got Mather AFB that has UPS and FedEx planes coming and going all the time out here. Similar distance to the landing and take off. Plus the military ones they fly for hours and practice- 2004LB7
