Are you sure you do not have another problem. Whitesmoke is usually from fuel starvation or cold firing.
If your truck is equipped with a block warmer plug it in. Also check fuse number 22 to see if it blown. If it is blown replace it. Fuse 22 powers the fuel heater in the fuel bowl. If the fuse blows again then the fuel heater is no good.
If the truck starts after having the block heater plugged in for 3 hours then you have a cold start issue that needs to be looked at. Either glow plugs are bad or glow plug relay.
There is no way to prime the fuel system other then cranking the engine over. I have been told this by several techs on here.
You need a minimal of 5 gallons of fuel in order to fire the truck up after you run out of fuel. Don't ask me why I do not know why this is.
