OK - last comment on the codes. P2287 sure makes it look like the ICP sensor or the wiring is bad.
Now - if you have tried disconnecting the ICP sensor in the troubleshooting process, then that might be the cause of this code.
Have you been trying to start with the sensor disconnected?
It is not uncommon for the ICP sensor and the pigtail to fail on the early model year (yours) 6.0L engines.
IMO the rest of the codes are not of any great importance right now.

I try to give more information than may be needed so I do not inadvertently leave something out.
I have not tried disconnecting the ICP sensor. I did not want to do anything until someone could enlighten me on what the issue(s) could be and what the next step is.
I will try that and get back to report when I have a chance to disconnect it. It may be tomorrow when I can do it.
When it was running I know the turbo would kick in but it was slow to pick up and go. Perhaps it is having an issue.
The injector #1 may be wiring as all 8 injectors were replaced at a local Diesel shop about 3 or 4 years ago. It was the failure if the #1 injector that caused the replacement. It totally went out and the truck was smoking like crazy. Had it towed to the shop and found another 4 that were on thier way out so I ended up having all 8 done.
I am not familiar with testing for the oil pressure, but the cost of replacing the oil pump scares me. The truck does not leak oil and does not use oil. I did notice in the past couple months that it was slightly blowing black smoke, when it never used to. The only time I noticed it before was under load like towing my 5th wheel and climbing a hill into higher altitudes.
In June and July we took the truck and trailer to Oregon and Yellowstone then back home to Nevada. The truck performed wonderfully and did not have one occurance that I can say may have led up to this.
I did have the blue spring kit delivered just now and wonder if I should do that while unplugging the ICP sensor? Is this even a factor?
I will get back with the hope that it is the ICP.

Is there someplace up front to unplug the ICP or am I going to have to unplug and remove the FICM and reach to the rear behind the turbo to disconnect?

Leaks in the high pressure oil system are ALL internal. You won't see those leaks.
I'll find a few videos for you.
I do Think your turbo is probably stuck (THE VARIABLE VANES IN THE EXHAUST WHEEL INLET) ..... in addition to your issues with ICP

I appreciate the help. I realized that I remembered where the ICP is when I was having the injector issues. I will have to get to that plug this Saturday. Either pull the coolant pressure container and the FICM or try to get the heat shield off from the bottom to get to it the plug.
If the HPOP I suppose I have to wait to see which of the 2 possible oil Pumps this 6.0 has. I see that depending on which end of 2004 it is on they changed. But fingers still crossed it is ICP and when I get to the turbo I can do the HPOP while it is out.
Will get back to this forum post after Saturday. Thanks again

If it comes to needing a new HPOP, I would buy an upgraded one from DieselSite.
It is expensive, but VERY reliable. Buying a cheap HPOP will have a high probability of giving you trouble!!
The early 04 and the late 04 HPOPs will "interchange". The late 04 is the same pump with SLIGHTLY modified internals to SLIGHTLY increase capacity. The late 04 HPOP will work fine in the early 04 engines. The 05 HPOP is the one that was completely changed.
If your ICP sensor is behind the turbo, then you have the early 04 truck with the 03 engine.
Be sure you get on the ICP sensor and not the IPR valve when you go to unplug it.

Sounds good. If it comes to that it will habe to be my winter project working between storms. Doing it myself will save a ton and then I can afford an upgraded HPOP.
I was getting confused seeing the two different pump for an 2004 6.0L.
Below pics are the 2 different HPOP's that claim to be for the 2004 - 6.0L Diesel. Are they really interchangeable? The top housing in the change out videos that I watched look totally different and connect differently, but go in the same location under the Turbo at the back of the motor.
Or am I totally off base and one of the listings are wrong?

That advertisement is wrong. That first pump (SKU:440-0014) will not fit in ANY 2004 model year. It is an error that sadly gets perpetuated by a lot of parts suppliers. That style pump is ONLY 2005 and up. If you try to fit that pump in an 04 you will be VERY sorry.

Okay. That is why I would never jump the gun and buy something without knowing what I am replacing. Thanks for the confirmation.
