The fastest I have found on my 6bt truck is to back off the nut 1/2 turn on all of the injectors. Then crank over the engine until there are no bubbles left coming out of the injector lines. As you are cranking, start to tighten down the nuts and the engine should start to run on the cylinder that you just cranked down.
Thats kinda the SOP for most diesel engines I have worked on.
