Hard start/no start hot

So my trucks been sitting for about two days ran fine started right away before. So today I go bout get in the truck and it just cranks and cranks and cranks. I unplugged the egr valve(for testing purposes) and it cranked for about 30 seconds then started. So I thought the valve was dirty and I should clean it. Turned the truck off after 20 minutes of running and now it won't start again. So I took the egr valve off(it broke while taking it off completely full of soot). Any ideas of what this could be? My ipr psi is at 30-35 while cranking

Did you unplug the ICP sensor on the valve cover and see if it would start?

You have an HPO leak somewhere in the system then. You're gonna have to air test it to find the leak. Most common on the 05+ trucks are stand pipes, dummy plugs or STC fitting on the back of the HPOP.

It looks like it is nicked and possibly a little of it missing.
