04 6.0 issues
Hi Y’all, have a new to me 04 f250 I bought torn apart with a bad hpop. I was able to get it all back together with a new pump and didn’t start first try as scangauge showed my icp at 66psi when off and when cranking no change. I unplugged the icp and it fired up but smoking pretty good like unburned diesel and have a few codes: p2285 from icp being unplugged, p0266, p0270, p0673,p0677, and p132b.
if i step on the throttle it won’t go past about 2rpm, would this be due to the bad/leaking injectors?
wanted to see what y’all think before I start throwing money at it but leaning towards replacing two injectors for the two codes and new icp sensor.
thanks!

After it started I took it down the block and it wouldn’t go past 10 mph with my foot on the accelerator pretty much floored, and definitely smoking a lot of white smoke that smells like unburnt diesel. The person I bought it from said they replaced all the injectors back in 2022. Thanks

ok so I've learned a whole lot and have dug more into this hitting a wall. I had the following codes: P2285( unplugged my icp as it showed 66psi koeo and no change when cranking), P0266, P0270, P0673, P0677, P132B.
I changed injectors on 2 and 4, added a new icp sensor(what a pain!) with ford oem parts from the dealer.
got it all buttoned up, cranked and fired up once, turned it off and didn't want to start and had the following codes: P2289, P0672, P0673, P0677. I checked the voltage of the icp with my scangauge and at koeo it reads 3270 psi and 3.84 volts. I unplugged it and plugged it into my old icp sensor and the volts are where it should be around .2 but still reads 66psi. does it sound like a bad icp sensor from ford? with the icp unplugged i was able to get it back on and idle for a while with these codes showing up: P0266, P2285, and the 3 glow plug codes.
its still smoking a good amount also, in park i can get it to accelerate, if i put it in drive it wont go past 1,000 rpms if the pedal is to the floor and smokes pretty good.
Thanks for any insight and help!

It could be a bad connect/pig-tail with an intermittent short.
P2285 is probably from start attempts w/ sensor unplugged.
Has P132b returned? That can indicate turbo control issues on 2003 engines and can have numerous root-causes (unfortunately).
When you try to accelerate, what do your ICP psi, ICP volts, ICP desired, and IPR numbers look like?

I thought about the pigtail but when i plug the old icp in and im twisting and turning it the reading is the same, when i plug into the new icp on the hpop cove it shows the psi around 3,000 and icv volts at 3.8. Will get a new pigtail to rule this out.
P2285 sounds correct as you stated as I have the icp unplugged to keep it running.
Code P132B was not back the last time I scanned it, I was watching vgtdc% and it was moving around from the 80 to 30 percent range. Turbo was replaced in 2022 as i was told and confirmed by sticker on it when i re installed it.
I will try it tonight once I get home, I have forscan and can monitor these points on my laptop and report back what I see in drive. I will not be able to see icp psi or volts or desired since i still have the issue with the new sensor reading high and have it unplugged.
thanks

At KOEO (Key-On, Engine-Off), there really isn't any way that you can have thousands of psi pressure in the oil system, so yeah - sounds like a bad sensor or an electrical short.
When you are running, the pressure might be high due to a sticking IPR valve, but you would just have to watch the data for that.
Just remember that the IPR valve % duty cycle is only a commanded value, it is not a real valve position.

I tried this when I first got it all together and no bubbles in the fuel filter bowl. Just got home and found a schematic so going to see if there’s an issue with the wires.

Finally had time to look into it deeper, found I had no continuity to the ground leg of the icp pigtail, found the connector to it bad. I used a piece of wire and two crimp on connectors to re connect(new oem pigtail is ordered) to test and i had the correct reading at koeo, fired up and idling it reads ivp V. 1.05 and ipr% 26.17. Looks like this was the issue for this code and squared away. I do still have the glow plug code for cylinders 3 and 7 i will replace, along with code P2066.
I did notice on cylinder 2 it looks like there is diesel as its clear leaking from where the exhaust manifold meets the head, cylinder 2 has a new oem injector so not sure what's going on?
I do still have the issue where if i put it in D and with my foot on the break it wont go past 1,000 rpms if the pedal is to the floor, the last time I drove it it did the same thing moving but I didn't try driving it last night.
Thanks again for your help and any further insight!

no more codes and still have the no power/boost issue. If I put in drive and power break it, it barely tries to move, if I drive it have no power and barely gets to 1,000 rpm and won’t go higher. Have a boost gauge on pillar but does not move. Any help appreciated
