11 international maxxforce dt no start

Have a 11 international dt that won't start. Bought the truck last a little over a year ago and had to rebuild engine after one month $$$. Few months later had to replace hpop. Truck hasn't been drove much but I was checking fluids on it and coolant reservoir had lots of oil in it. Oil level hasn't dropped alot nor has the coolant level. Figured it was oil cooler. Was gonna move it into shop and it will not start. Sounds different when cranking as well. Will not even start on starting fluid, not even a little bit. It does not build oil pressure while cranking. Codes are engine exhaust valve actuation system oil pressure, brake switch, and engine turbocharger 1 outlet pressure. SPN 4287, SPN 5541 and SPN 597. Any suggestions. I have $90k invested in this truck when it's only worth around $30k. It's getting a new home if it gets running again

 

Yeah we bought it used for $40k. It's a rollback tow truck. Cost us $28k for rebuild. $6k for hpop. A few more thousand for odd and end things. I over exaggerated $90 a bit but for what we have invested we could have a brand new truck

 

It says it can show fuel pressure but doesn't. I just got a cheap diagnostic tool. Got any suggestions on something that will read icp and fuel pressure? Not sure what sensor this is but we replaced a sensor on the back of the hpop twice. Think it was the ipr

 

Had to replace hpop in my rig and one of the things my mechanic checked before replacing hpop was some oil rails under the valve cover. Said it was common for the orings to fail. But I'm sure your new head came with new stuff
