Error code p2623. ICP or IPR? Help

Hello, I recently picked up an 04 F250 6.0L diesel with 144k. She's been driving fine since I got it. I went to start it the other night and it wouldn't turn on. It would crank and crank and crank, but not start. Finally, after continuing to try it decided to start up, but with the check engine light now on. Drove it a bit and it drove fine, no sputtering, odd noises, hesitation, or anything of the sort. But once I turned it off it would not turn back on again.

I used my scanner and it had one error code present, which was code p2623. Code says Injector Control Pressure Regulator, circuit open. I did some research, but it doesn't seem to be very clear. Some say it's the IPR, some say ICP, some say both, and some say you're screwed and it's your HPOP. My ICP is located in the older model location, which is under the turbo. From what I understand the IPR is located basically in the same spot. I don't want to just throw money away by replacing something that didn't need replacing. Which would actually cause this particular error code? Is there any way a regular guy can check/test to be sure? Any input would be much appreciated! Thanks in advance!

Given the mileage, I'm gonna venture to say your pump is the problem. The 03 pumps had the most issues and you have the 03 engine. Best thing to do is pull the IPR and see if there is any damage to the screen.

Well, we're gonna keep our fingers crossed it's not the pump. Lol. And I'll pull the IPR as soon as I can and have a look see. Thanks for the info.
