yj 5.3 nv4500 help

I put a 2000 5.3 and gm early style 93-95 nv4500 in my 89 yj, using new stock jeep mc and a slave for 93 Chevy pickup, I bled the clutch n drove it, shifted alil rough but worked, just figured I needed to bleed more, 2 days later I went to move it, and had no clutch pressure, tried bleeding it in multiple ways even power bleeding, replaced everything mc sc and line, still no pressure, fluid just moves up in the reservoir when you depress the pedal. I'm outta ideas what to do now

I think I got it figured out. All the wires coming out of the yj pcm were throwing me for a loop. I had a whole bunch of key on 12 v wires and only need a few. Cutting the pcm out now. Just for anyone else that wants to know you can delete all wires coming from yj pcm. Looks cleaner and safer with less wires to possibly short. There are two diagnostic ports next to the battery support that can be deleted they mostly run to the pcm

As far as the master and slave problem you are having I wish I could help more but I don't have mine running yet. I would drop slave from clutch and see if it strokes. Could be throwout bearing fork

Oh I got the clutch, it was the master cylinder again, 2 brand new masters were junk, used a speedway one I had sitting around, worked immediately
