Puking Black Smoke - Now she won't start

[Waz 6.0]

Replaced all 8 injectors on my 2003 6.0 almost 2 yrs ago. Over the 4th was driving home from Duluth, MN to Mpls when my truck started puking black smoke. No noticeable loss of power, though. I was pulling a 24' car hauler and made it back home.

Once home, I changed the oil with RotellaT6 and added 8oz of Rev-X, thinking it might be a stiction issue (and not wanting to drop the cash for injectors again). After the oil change, it started up fine and sounded smooth, then quickly went South and sounded like it wanted to die, ultimately, it did die on me and won't restart (at least not while it's hot - haven't let it cool off yet).

Before it died, I tried driving it around the block - it had ZERO power - much worse than if it had blown a turbo boot - I mean no power at all. I could barely get up to 10 mph. It died for good as I tried to back it into the driveway, and there she sits.

Thoughts?

Sounds like a possible FICM issue check your voltage on it.

I'll check the ICP sensor as well - thanks!

The ICP should read 0psi with key on engine off. If it is readying anything other then its bad.

So, I replaced the ICP sensor and the IPR valve. While I was digging into things, I did the Fuel Pressure Regulator Upgrade Kit (Blue Spring). I just started and idled the truck for the first time - I warmed it up for a while (normally at this point it would start to cough, sputter and die) and whatdoyaknow, it ran great! Haven't road-tested it yet, but I think I fixed the original problem - having it die once it got warm.

However, I'm POURING black smoke out the exhaust. My wife was driving home and she thought our house was on fire. I mean it's thick and now the whole neighborhood smells like diesel.

Could this have something to do with the new ICP or IPR? Could it be the blue spring?

I have converted it to run on veggie oil as well, using a completely separate fuel system. Perhaps I should switch over to veggie to isolate the fuel system and see if I still have the smoke?

Any thoughts?

I should mention that I had just changed oil prior to this and added Rev-X for the first time. Could it be that I had a stiction problem and now I've added a cylinder that wasn't firing before, burning off crap?

And FICM tested out okay. 47.1/47.5
