Thinking IPR related
Alright folks, I got home after work and hooked the scangauge up to the truck. KOEO my FICM was reading 48.5V, IPR was reading some negative in the 3,000 range, my SYNC was a 0, and my HPR (which I don't remember what that was when I setup the scan gauge) was reading but I don't remember what.
I started the truck after sitting all day still and it fired right off but could tell something was off. As it ran the FICM was holding steady at 48V to 48.5V really only fluctuating during the crank to start the truck. The IPR was up to I believe 3,000+, and the HPR was in single digits I believe. Sorry I was trying to watch all the numbers and didn't pay close enough attention to any of them like a fool. As I allowed the truck to idle it did what it did this morning and continue to run rougher and rougher, as this happened I was able to watch the IPR go from 2400+ down to 2200+ down to 1900+ and so on. I shut the truck off and now it will not start. I get some hard cranks and everything but no fire. The IPR won't get above 2200 now during cranks.
So if my looking around on the old interweb is correct I may have a plugged screen or a bad IPR correct? Could it be worse than that? Is this just the tip of the iceberg? If it is just as simple as switching or cleaning the IPR how big of a job is that? I'm not exactly helpless on wrenching but I am by no means a competent engine builder either, probably closer to helpless lol.
Thanks for any help and suggestions guys. I will also be contacting the diesel shop that helped me track down my bad intercooler last year and see what kind of phone diagnosis I can get tomorrow also.
