what happened was the filter sock on the pump completely came apart and the trash of it was being sucked through the fuel system. when I pulled the pump it was completely gone and I can see particles of it everywhere in the gas. new pump, a few new filters later and the engine codes went away and truck fires right up.
maybe something to look at?

I too thought that the FP might be bad. I checked the pressure during prime and cranking and it seemed ok. 55ish psi. Haven’t checked while driving. It really fires right up with no hesitation. I’ll keep an eye on it though.
