Ok a little update. I got it back together and I am still getting a ton of codes erase them and some come back sometimes and all come back others. I went through the wiring trying to find a short somewhere. The only thing I found was on the 3 plugs going into the FICM the wires were kinda stuck together I couldent tell fully but they looked like they might of been fused together from heat? They dident look very bad it was only where the wires touched another wire. I am going to dig into that a little more. As far as the ref voltage test I am trying to figure out this code reader I am looking for the instructions right now. I tried to perform a KOEO test and it couldent complete it for some reason. I am not sure what this test is supose to tell me but its having trouble with it. My code reader is a innova 1003 diagnostic tool. I am going to look more info on it online to see if it can perform this test your talking about.

Ya might be worth a shot to backprobe the ICP sensor with a DVM see if its getting 5volt refrence signal and you should be able to backprobe it while cranking and get a voltage reading that can be converted to pressure I beleive you need .80volts to start
It maybe worth going to autozone and getting a scangaugeII and that will be able to tell you alot upto like 40-50gauges depending what you want they work great on these 6.0s and then you have the other code reader for OBDII codes
It may give you some direction to go in atleast

that is odd the ficm wires are all jacked up. And it had to of happened B4 the work cuz it hasnt ran since so it never got hot. were you having running issues b4 The work or was everything fine.
The scangauge wont be able to check individual injectors like that you would have to have an auto enginuty to be able to BUZZ TEST each one
But the SG will check ficm main power, ficm vehicle power,ficm lodgic power,ficm sync ICP,IPR,MAP,VGT,VOLTs,CMP/CKP SYNC,EOT,ECT,V-REF,BOOST,TFT,FSS
you will be able to see alot of the main stuff

I ordered a new icp connector but having trouble finding the IPR connector. not to worried about price at this point just want to get it this weekend. Does the dealership carry this part? I cant find much online. I called napa they said they can get one by tomorrow for 7.99 but that seems cheap and I just dont think its the same thing I need.

OK I replaced the ipr connector and it got rid of the p2285 code but im throwing some glow plug codes and it still willnot start. Its not throwing random codes anymore either so thats a huge step forward I think. Charging batteries right now again.

BLAH!!!! Okay I checked voltage while cranking on the icp I am getting 0.030 vdc while cranking The meter is a bran new fluke I use every day I know its good. I set it for min/max and that was the high while cranking fully charged batteries. I unplugged the icp after that and wouldn't start still. So if I am thinking about this correctly the only thing left would be bad HPOP or bad leak? I could use a little more guidance on what to do next. I am thinking starting to tear everything back apart on the passenger side get inside the head and check the oil rail and oil lines. after that turbo off and open up the hpop? Is there a way I could of broken something taking off the Stand pipes I bent one stand pipe slightly when removing it. It wouldn't break loose. I replaced with new stand pipes and they went right in. All opinions are greatly appreciated

well that sucks
one wire should have been 5 volt ref other wire ground and one wire return signal the .030volt one.
but at least you have some direction to go in
I cant remember but you had good oil flow to the oil filter right I just skimmed thru the thread and didnt see it but didnt you check that B4
It might be worth it to rig something up to air test the HPO system

Blade I feel like when this is done I need to send you a nice bottle of whiskey or something You have been so willing to help. I gotta tell you I am starting to get a little bit worried. I have been in the tech folder researching the high pressure oil system. I forgot to check the 5v ref wire I just checked the red and green wire for the .8 volts to start. I guess I will have to round up a couple hundred bucks and buy a scan guage will this give me hpo readings? I could always plug the icp back in and check the ref voltage if you think that might still be a problem. I dident check it because the code never came back. I have an icp pigtail on the way just for safe measure. I am still trying to figure out a way to test the hpo system cause im not sure if the scanguage will do this. The icp is such a pita to get to I plug it in and unplug it with a screwdriver its a 10 min ordeal lol. one question. If im not getting .8 v cranking and the truck wont start when its unplugged does this point to a leak?
