Yep, my dad's old farm truck (also 1999) GMC 2500 did the same thing with the smoke show, and exact symptomology. We changed the glow plugs, and relay (just because), and that fixed the issue.....no more smoke show. Ran smooth when cold (albeit noisey) and even better when warm.

You haven't seen smoke till you crank one up at -20 or colder ,and talk about noisy !!!
