[QUOTE="Long Gone, post: 1528575, member: 31343"] Thank you for the input Zeb and gohouston. I have got those numbers backaswards there for sure, sorry about that. I have suspected that it might have something to do with the ICP, but I was not getting my head around it as the lower value at around 27ish would be running the IPR pretty near closed,(as I was thinking that would still be open a bit) and I could see that would lead to the higher pressure but now as you point out and I am finally remember it if you unplug the ICP it defaults to closing alright, and 27 is closed not just kind of close. Thank you I will get right at looking at that connection etc. I am not getting any codes. I wouldn't think it is anything in the injectors as when it first starts up it will run fine for almost 10 seconds. When I changed the HPOP I pulled the HP oil rails and flushed and blew them out real well. Also blew out the HP oil tube supply lines from the pump through the braided hoses into containers so nothing would get back into the head/block. I tried to suck out the injectors with a turkey baster also but don't think it did much. Did find some things that looked like bunkey balls (repolymerized HPOP screen) in the initial draining of the driver side HP oil rail (the first I pulled), but didn't find any thing more in the drain, cleaning and rinse cycles of the other, nor in the lines. My gut feeling has always been that it was something electrical and I think you have confirmed that, and I know where to go now. I would be surprised if there isn't any oil on that plug. Thanks again. [/QUOTE]
