I'm having troubles

2000 with 160/30's that have been in since October.
Out of the blue it refused to start the other day and got towed here.

ICP maxes out at 300psi at 89.9% DC
So I pulled off the valve covers to look for injector leaks, couldn't see anything
Pressurized the rail with air and couldn't hear anything except a little gurgling in the oil pan.

So must be IPR right? Nope. I put my IPR in his truck and no start. Put his IPR in my truck and she fired right up. So I switched that back.

That leaves the hpop. So I switched the HPOP with a known good one I have and still nothing.

I've noticed that icp doesn't budge from 0psi until the IPR climbs to 89.9% and then the icp slowly climbs until it hits 300+/- psi and stops there.

Do I have to pull injectors one at a time and look for oring tears? Anyone think of anything I'm missing?

Did I understand that right?

You put your truck's IPR in your buddy's truck which I assume was running up to that point and it didn't start?

Your buddy's truck's IPR in your truck made your truck fire right up?

Unless I am misreading something it looks like you have a bad IPR.

Sorry, that may have been unclear.
My truck is fine, buddy's truck getting worked on. I ruled out the IPR by swapping them and both work in my truck, neither work in his truck

this is similar to what your truck was doing a while back right?

Have you applied 12v straight to the ipr to rule out wire or PCM problems.

@Steve604 - It's similar to mine, except when my injector o-ring leaked it was very easy to spot by the oil oozing out.

@sbluke55 - I want to try that, but im finding mixed reports of the correct way to do it. i have very close to battery voltage on the one wire, and the other wire is the one that gets the signal from the PCM.
Some say to jump it with 12v, others say its a modulated ground circuit and to ground it out fo close the IPR.

I dont want to wreck it by doing the wrong thing. but thats what I'll try next

300 seems kinda low on icp to me... have you dead headed the oil rails to check hpop? Is there metal filings in oil filter?

I replaced the hpop.
The fuel has no oil in it. Rails seem to hold air.
I'm thinking it almost has to be wiring.

i think that a wiring issue would give you associated trouble codes

did you try hitting it with your purse?

There should be DTCs there. ... I wish we could hook our IDS to it and get a good reading on everything that pcm is seeing....

I will talk to my boss about it monday but in the meanwhile I'll keep thinking
