You should get spurts of fuel out of the injector lines instead of trickles. I would make sure the rack is moving back and forth freely. Your governor could be stuck at fuel shutoff (rack locked to far right as you look into the IP housing) when you pull the throttle open the rack should move to the left at near full fuel position since there is no opposing force from the governor flyweights.
If the rack is moving and you still get only trickles then I would start at the tank and assure full fuel flow at each point in fuel delivery. It is not necessary to bleed the lines at the injectors, at the top of the pumps or using the bleeder screws behind each injector line is just as good.

i agree with the above post. the only thing i would suggest is to install a thermostart in the intake manifold to help with cold starts and forget the either. they are cheap and easy to install. example-----https://www.amazon.com/Diesel-Thermostart-Intake-Manifold-C5ne9a436a/dp/B00D6OGN3U
ccjersey: thanks, your reply was detailed and concise. Very informative.
bursitis: Thermostart; thanks, good idea (why didn't I think of that?!!)
Where in the intake manifold would you suggest is a good location?
Generally just opening the injector line lets the air out after changing filters. But several times I have had one that just didn't start even after pressurizing the fuel tank. Opening the bleeders on the back side of the pump seemed to do the trick.
Metalman, I look forward to your starter pics on your installation.
I have had good luck with a small open end wrench on the bleeders behind the injector pumps, no special tool needed.
Also, what are you temperatures there now? My D2 ( electric start conversion) will literally start in 1 second with no ether and air temps above 70. Below that about a 1/2 second shot gets it going. ( but, it's never below 40 here)
I think you are looking for black smoke to know you are nearing- or getting- diesel combustion.
Why is it all these hard/no start issues want to ignore fuel transfer pump pressures????
What pressure will you get at cranking speed OM? if fuel dribbles out of the injector lines when cranking, there will be some pressure to start.

I would first look for a plug i could remove. i would also try to get it above the manifold where it splits up to the individual cylinders.
