IPR problem???

So I have a 6.0 (obviously) So far I have done EGR delete, HPOP, oil cooler, ARP studs black onyx gaskets, 4" turbo back exhuast, stand pipe, cold air and probably a few other things just for a little back ground.

The other day I was driving and truck would lose power really bad like it was almost dead. Did this 2 or 3 times over about 35 miles and finally died while continously driving about 60mph. Couldn't get it started checked a few things and decided to ave it towed to the shop. They ended up replacing fuel injector control sensor, although reciept says ICP sensor.

Truck ran great for about 60 miles and now is dogging exactly like it was before it crapped out on me. After talking to a couple friends they think it could be my IPR valve apparently they think these 2 things work togehter.

What do you guys think I should check? Getting ready to check the voltage on my FICM, but what else should I check? I am somewhat comfortable working on it but not great diagnosing anything newer than carburated gas motors (aside from your regular BS like water pumps and alternators)

Please help I am really starting to HATE my truck.

Don't hate the truck!

If you recently replaced the oil cooler it is possible for debris to get into the passage underneath the oil cooler. That would explain why it ran fine for a while because it needed time to go through the passages until it got clogged in the IPR valve/Screen...

When the IPR screen is clogged it will kill your truck and you will not be able to start it because you will not have enough oil pressure to fire the injectors.


My suggestion is, take out the IPR valve and check the screen on the end and make sure it is not 1 damaged/broken or 2 clogged...
It does NOT take alot to make it stop working.


Mine had a crack in the screen the size of a ball point pen tip if not smaller.

The oil cooler and hpop were about 3000 miles ago and it is runnig right this second, but I doubt it will long.

Next question lets say IPR is clogged cracked or broked and I just did ICP sensor, since ICP sensor flashed a code the first time and was replaced and ran fine for little bit, do I replace it again or only if it throws a code?

I believe I will tracking down an IPR removal tool tomorrow.
Also is there a thread with the how too on IPR removal. I searched but didn't find it?

I wouldnt't replace it yet.

My IPR screen was cracked open... I replaced the whole IPR valve (because many shops around my area that I talked to said they have experimented with just "cleaning the IPR out" and replacing just the screen and Failed)

They have started to just replace the whole valve...

Back to topic, when I replaced the IPR valve I DID NOT replace the ICP sensor and it fired RIGHT up without a glitch!!!

The ICP is a sensor only reads pressure and reports to the PCM. The IPR on the other hand is a regulator that its parts actually move. Once the IPR is changed you should not have to change the sensor again.

I know the IPR is a regulator (injector pressure regulator right?) I know the ICP is a sensor just got it changed yesterday. The reason I asked about changing it again, is it is having the same symptoms.
Thank you though I hope your right and don't have to put another sensor in it. Do you know if there is a sticky or anything on removing the IPR?

So I can't get my truck to throw a code, and before I just go and try and replace my IPR is there a jr shade tree mechanic test for the stupid thing. I just don't really want to spend several hours pulling turbo modifying a 1 3/8" deep socket and everything that goes with pulling my IPR to find out thats not the problem.

Does my reasoning for thinking my IPR is clogged cracked or otherwise even make sense?
Any suggestions on what else I should be looking for?

If this is an '05 or newer 6.0L, it could also be the STC fitting leaking if it runs worse when it's warmed up.
