are you using the hand crank?
if so, try to crank the engine without the compression release, you should have a hell of a time getting it to crank over
that would tell me you have adequate compression
also just because the injector appears to be putting out a decent spray pattern, it may not be doing so when pushing against compression, you might need to increase the injector spring tension a bit.
does the engine put out smoke while you are trying to start it? if it is putting out smoke you are likely getting enough fuel, but it might not be atomized and increasing the injector spring pressure a bit will help.
the right way to check the injector of course is to take it to an injection shop and have them test and set the pressure that it pops off at.
i also agree that you might well do better to get a pulley mounted and spin the engine up using another engine, sometimes you just need the added rpm to get it to light up the first time.
very hard to diagnose this sort of thing from a keyboard/puter screen
fwiw
