Tay, I have a F350 and just got through dealing with similar issues. The white smoke is typically caused by a bad gpr or gp's. I'm assuming that you don't have the white smoke issue once it gets warm.
It may be different with the LMM but I thought I would mention this since a gpr and/or gp's are a lot cheaper than injector(s).
Do you have a block heater? Can you plug it in overnight and see if you still get the white smoke?
