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?
