How old is the truck? White smoke can be caused by low compression, retarded timing, or low cetane fuel.
I would start by purging the fuel and installing fresh filters, especially if the truck has been sitting for a while, and running the engine on known good fuel.
The DT 466 has had at least four fuel systems over the years, the Ambac Model 100 rotary distributor pump, the Bosch MW and P Pump, the electronic HEUI, and the G2. Retarded timing or air in the fuel system will cause white smoke. Make sure there are no O ring leaks and that the return checks are functional.
A worn out power cylinder will have inadequate compression to support combustion. Hard starting is the first symptom, but white smoke follows.
Pull the valve cover and check valve lash. Worn valve train components can cause issues too.
