What are you using to scan the truck? You will need an ids or equivalent scan tool if you want to get the hidden codes.

Emissions can cause no starts, but it shouldn't even crank if that were the problem. What is rail pressure while cranking? The pcm needs 5kpsi from the hpfp to idle(or even start), but without a good scanner there is no way to get codes. And any time you have a crank no start there will be codes...
