Cummins problems HELP!!!

[MandBtrucking]

I will try all that stuff yes it smokes on start up and in between gear changes I use the lift pump to start the truck I have tried running it down the road doesn’t seem to help at all it won’t start without it being on at all that was my first thought was it is loosing prime but it shouldn’t take that long to work the air out of the system should it?
