Truck throwin codes-ICP and IPR

truck specs:
2000 F250 7.3L

truck ran yesturday for about three blocks and died. Had to get it towed back to the house. Changed the oil with 15w40 and put some 47 cetane (BP) diesel in it because it was at a quarter tank. Checked fuel bowl just in case there were jelling issues.(sorta cold hasn't dropped below 20degrees) None found. Let it sit a little bit and tried to start up again. Reved for about 30 seconds or so and then a slow start/shaky ran fine after that no codes.

Come out this morning, hard start again go to the gas station (47 cetane BP diesel different BP though) go to start up the truck, really hard start after holding ignition key for longer then I would like (50seconds or so. Don't want to wear out the starter) and cycling the glow plugs. Starts and runs but is throwing check engine light.

P1282-excessive ICP
P1212-ICP Voltage not accepted
P1211-ICP Not controllable pres or above/desired

Ok I did some research and people are saying these codes usually correspond with issue with the IRP sensor. Although some have replaced both ICP and IRP. Got a quote from Ford for the IRP and its gonna run 360$ and the ICP is 170$. Talked to a fleet mechanic up in Fairfax about it and he said the IRP is a ***** to get to, need a 1 1/4 deep well socket?

Any idea which it would be, ICP or IRP? My big question is are there diesel places around the fredericksburg,VA area that can test oil pressure and things like that? Most of the shops I have talked to can't do it and if they can't do it I don't know how they are gonna fix it unless they are just replacing both sensors and charging me for it. I really would like to avoid going to ford since I don't have a ton of money to spare.

First check the UVC harness connections at the rear inside of each valve cover, look for burnt or loose connections. You can pull the ICP and see if there is oil on the connector, if there is it is bad and should be replaced, but you can unplug it and the puter will default to a value of 2500psi and the truck will run. I also think you mean the IPR instead of IRP, it is the Injector Pressure Regulator.
