One more thought, if you still have the fuel bowl and removed it to replace the hpop, did you pull your filter and cycle the key?

well youve definitely got an oil leak somewhere.
I had a rr and running two sd pumps. Still got 65 psi

If a injector was stuck open would I get smoke?

You probably just introduced even more air into your hpo system. Are you saying you pulled the line off and cranked the truck? If so, you should have a huge mess. Have you checked the engine oil level to make sure you have enough oil to even fire the injectors?

why do i feel like that HPOP was good but is now bad. and if it was stuck open it should be pouring fuel down into the cylinder.
That's what I was thinking. I just pointed the hose into a pan and it just "pulsed" out when I cranked. I was expecting a mess.. Oil level is good.

Yes, but 7.3 injectors arent really known to hang open. Now it is possible for you to have pinched an injector o ring, or the injectors to be so damn worn out that they wont let enough oil pressure build, but I doubt thats your problem. 9 times out of 10, people have left something unplugged, or just havent cranked enough

i feel like he cranked it enough. cranked it enough it sounds like the starter is gonna go next.
I ran it with my 300/200s and just took it out to because I got a srp1.1. It could be the hpop.

Then he found the weak link. Lol, out of all the trucks ive worked on, ive just cranked and cranked, not caring a whole hell of a lot about the starters, because of they go bad, we would just replace them, but aside from my personal truck, ive never killed a starter from extended cranks, and like I said, ive basically tried to kill them before and couldnt do it

You are bleeding oil pressure or the pump is bad. I would be more inclined to pull the VC's and watch for leaks while cranking than swapping ipr valves and suspecting oil pumps at this point.
Have you tried cranking with the icp sensor unplugged?

is this a new srp 1.1?
No. I sold it. I am putting my truck back to stock.

I ordered a new IPR. I got to thinking, I don't remember seeing a needle between the body and a actuator when I cleaned it as described in this:

So do you still have the srp?

he said he sold it above lol so when you split the IPR you don't recall seeing the needle in there or fall out? its tiny so super easy to loose it
