Fuel issues 2014

[Mavrik-The-Gent]

Truck died.
Diagnosed as a bad lift pump. Has less than 2psi.

Couldn't get one, so I installed an air dog aftermarket system, works great.

Upon checking the HPFP I noticed the quality sensor had a metal piece or two on it. So I replaced the pump to avoid any issues.

I also removed the fuel rails and inspected them. One at a time. Found no metal filings.
I removed the fuel filter and found none either.

I now have a crank no start issue. Was told by a local Mopar guy that I could just crank and go.

I've replaced high pressure pumps for Deere and we had to bleed everything.

Ideas?
Fuel pressure regulator?

Any ideas? No local shop will touch these trucks so I'm pretty much on my own. The dealers are useless.
