What year is your truck? Sorry I read your post too fast, I see you have an '06. Also it is not unheard of to have a bad replacement HPOP, especially the early style pumps, the later style that you have is much better and seldom fails. It sounds like you still have a high pressure leak. I would pull the valve covers and do an air test, use a stethoscope to help locate leaks. If you can't find any leaks you can use nitrogen to pressurize the system to higher levels, I have found leaks that way that did not show up with shop air pressure

You or a shop needs to get the truck hot and air test it to find the leak not blindly replace parts. The 05 and up pumps are very stout and it’s not that common for them to die unlike the 03-04 pumps but it does happen but there’s a good chance the pump they changed was still good. You have a high pressure oil leak the air test will find it it sounds like it would be a good idea for you to find a new shop to do this though. How did they test the injectors? Why does the 2nd opinion guy say you need a new ipr? Your ipr does need to come out to put the fitting in its place to air test the high presssure oil system. I wouldn’t buy one more part till it’s been air tested or your just pissing in the wind and it sounds like enough of that has already happened. There are plenty of videos on youtube on doing the air test if you want to see how it works or let your “mechanic” watch it.

Have you unplugged your ICP, then tried the hot-start?

That's absolute BS. First off you can do a branch tube in frame, secondly if they do have to pull the motor that's no less labor than swapping in another one, and the branch tube and rear cover seals are a lot cheaper than another engine. Good call getting the 2nd opinion.

On the IPR, if the tech pulls it and the screen is covered in lint or broken it doesn't matter it's only 100km old, he'll want to put a new one in. I don't know of an "official" bench test of the IPR valve, so someone who makes money flagging time is going to swap the part instead of wasting an hour.5 of labor dicking around with trying to rebuild a part that he can replace for the cost of him playing with it.

That's if the tech uses the Accurate Diesel or TamerX IPR plugs.

If the tech uses the OTC adapters the book calls for in the ICP fitting he'll either have to jump the IPR closed (and potentially burn it out like maybe the dealer did?), or use the OTC IPR controller.
