This is what i would try (cheapest first) redexe/wyyns
injector cleaner,double dose,then i have put 1gal gas in 10gal diesel to increase burn temp (you may encounter a hot start problem temporarilly)then if still smoking, get a compresion check on the engine(this will tell you volumes)
by the way the NATO tanks put in 1/3 gas in diesel to stop it freezing in arctic conditions.any more than 1/3 can result in problems.

hi, i have seen this problem ten years ago twice, but i was dumbfounded by the answer. all details aside, I replaced the ecm, and never had the problem again with both of them. this repair was a recommended repair by the local truck depot in my town, they stated the ecm got hot along with the truck and it lost the injector sensor signal. now, don't take this solution and run with it, i haven't repaired a 6.2 diesel in ten years and i maybe off track completely. but at least maybe you could ask around your town or maybe a large truck facility about this. of course, you should take to a shop to have diagnosed. hope i could help.
