Sled Dog, Gen 2 stuff, right?

I assume you bled the fuel supply line first... bumped the starter to induce the lift pump to purge the air from the line.
Since you started with a new (dry) VP44 you should then:
Crank engine for 30 seconds at a time to allow air trapped in the injection pump to vent out the drain manifold;
Clean around injector fittings where they join injector connector tubes;
Bleed air by loosening high-pressure fuel line fittings at cylinders number 3,4 and 5;
Continue bleeding injectors until engine runs smoothly. It may take a few minutes for engine to run smooth;
Tighten fuel lines at injectors to 28 ft. lbs.
