I am a total noob here but have read 100s of hours of posts in prep to buy a truck. From my reading it could be a number of things but either injector problems, FICM issues, factory FPR could all be culprits. I am sure some of the experts will have better ideas. If you can check the FICM voltage and its above 47.9999v you can eliminate that. Any puking around the degas bottle to indicate a pressurize cooling system (bad egr cooler, bad oil cooler, possibly shot head gaskets since you said it smokes alot). Another good test after you get it running again is to get it up to temp and put a scan gauge II on it and see if the temp difference between the engine coolant and engine oil is over 15 degrees, if so you could have shot head gaskets and oil cooler/egr cooler issues.
Sounds like injectors to me though.
