Just Changed injectors, how long to purge air from system

[DuramaxPowered]

I just swapped out my stock injectors for a set of 60 overs. I crank the truck, but have a " no start" condition. There is white unburnt fuel coming out of the exhaust, but the truck doesn't want to fire up. How long does it take for air to be purged from the high pressure fuel system? I have the scan tool connected while cranking, but only build 600-700PSI rail pressure.

iirc you need atleast 5000psi to start.

yeah, I talked to a buddy who did injectors, and he said it would take a while to get it to start. It's starting to fire now, but I'm only cranking for 10-15 seconds because I don't want to burn up the starter. I'm letting the starter cool for about 5 minutes between cranks.

you need at least 1,500psi on the rail for the engine to start

It's starting up right now within a second or so of cranking, so it seems that the air is out.
