The trick being that if you can get it to 'run' on easy start for a few seconds, any air should be pushed out of the system.
Best bet is to bleed it right up to the injectors the best you can, then go for it with the easy start.
Not too much though, and don't be tempted to use brake cleaner or carb cleaner instead.......... tried both in the past with engines running at 9000 rpm, clouds of smoke and lots of knocking
Certainly bled the air out though
