Default Afm lifter issue

Just replaced all my lifters and the valley manifold. Started it up and have a miss on #1. Have spark and fuel pulled the valve cover and found valves not working. If I crank by hand with intake and valley cover off they work fine but put it all back together and they stop working. I have unplugged the new valley manifold and it will run in V4 mode. I am at a loss here and looking for ideas...

Welcome to the forum...
Isn't the lifter hydraulically activated, no oil pressure and it won't work....?
Just a thought....
