What now??????
So to recap, truck overheated, put a degas bottle on it. Low power, hpo leak+cyl#1 cont code. New orings on rails, ICP&IPR act crazy and no sync. check again and now ICP&IPR look almost normal, cyl #2 cont code, and still low power? Have you read throught the low power thread in to Tech folder? https://www.ford-trucks.com/forums/s...d.php?t=964020 might be some insight there. In the meantime here's a bump.

I may have read 1ICP on the SGII as 11. The recap is good except I also put a new hose from TS to degas bottle (it busted) but I think the split in the degas bottle was the cause of the loss of fluid. Looking at the folder I am going to remove the IPR and see if the screen is gone and if the plunger if stuck open by trash. Will start disassemble tonight. Would the low pressure cause no sync. or is that another issue?
Thanks for the help.
Got everything off up top to see the IPR. The ground wire that attaches at the back intake bolt feels very weak at the crimp end. Going to replace it. The plugs to the IPR & ICP looked good, no oil anywhere. Pulling the IPR tonight, then I am going to get the O'rings for the STC connection at the oil rail and replace it. With the P0264 I figure to pull #2 inj. and have it checked out at a inj. shop. After that, I guess on to the oil cooler. Will update.
Thanks for the assistance.
The Givaway was IPR% at HIGH Idel should be 40.60IPR% YOU HAD 54.7%IPR
Like Rusty says ICP should be 0 at KOEO maybe it was 1 ICP if I understand right
Post ICPV at koeo now
it should be 18-24Volts at KOEO
below is Ford Values for ICP and IPR%
the last 2 numbers with the ----------inbetween them is operating Range dont worrey about those
ICP 0.2 1.0 1.8 0.15 - 4.7 VOLT Injection Control Pressure
ICP_DES 0 625.5 1400 - 1450 0 - 4045 PRESSURE (PSI) ICP Desired
IPR # 14.84 24 40.60 0 - 50 PERCENT Injection Pressure Regulator
You need to AIR TEST HPO System Now
How much volts is the FICM Putting out???
And what other DTC/Codes did you have before you cleared them???
This might be the 3rd problem

I removed everything last pm to get to the IPR. The FICM connectors are secured with zip ties, the ground wire at the back of the intake manifold feels like it is gonna break where the eye is crimped(was going to replace). I was gonna remove/check IPR, replace if bad. Then fix ground connection, install new O'ring on STC fitting at HP Oil Rail (driver side) and then check for oil leak by providing air to fitting at STC on driver side. If a leak, find it. No leak, put side back together, crank and see if P0264 code appears because of possible ground connection. SGII records FICM at 47.5-48.0 vdc. With 200+k miles I was thinking of going ahead with HPOP and injector replacement, Oil cooler replacement because most everything else had been replaced.
Do have 403 & 405 codes but the EGR had been deleted by previous owner.

.Not sure if you know but cheezit- who mentioned the oil pump above^^ - is a Ford Tech with much experience on these trucks.
Does it require a special O'ring? Do you think it could be the cause of the high IPR reading and loss of power? Bought a thermocell for the skeets, works great in a 5-7ft circle but it was under the hood and they were gnawing on the legs. Maybe cheezit will chime in, been working on this thing since I bought it. Enterprise if around Dothan/Opp area right? I have relatives in Evergreen, grew up in Mobile (ages ago)
Thanks again
On the o-ring, i think the IPR is different on your '04 but on my '06 there are two just at the edge of the screens cap. One looks normal enough but but may be hi temp rubber given where it's at and the other is square shoulderd and labeled as a "back up oring". Also thers a regular oring on the base where the threads are. I got a screen kit from the dealer. It came with all four parts and cost a little less than $50.
if the Pump Bad you will hear Air Girggling in oil filter housing also listen valve covers for air leak and dont do it to Fast the air needs to work past oil do it multiple times and give IPR a Break after each time DONT BURN IPR UP
I betting Cheezit Nailed this one
