Okay just swapped my lly out for another. Got everything all together and was priming the fuel system by compressing air into the fuel fill for the tank. Primed the fuel system up top from primer pump till it got hard started cranking almost fired and it suddenly stopped like hydro locked. Put bar on crank and could spin motor either direction, pulled glow plugs thinking it might be hydro locked on it and none where wet. Not sure where to go. also loosened starter and moved back away from ring gear still couldn’t get it to spin.
Motor won’t turn over

Pull valve covers and check valves. Sounds like you may have dropped something into the motor and it got hung up in a valve or is caught between the piston and head.
I will definitely be checking into that. The motor came from a supposed running vehicle and came with everything but turbo. I put my turbo on it and wire harness then dropped in. I feel that if it was hydro locked on one cylinder or something was in one it would spin backwards. My thoughts are possibly hydro locked on either coolant or fuel in more then one cylinder. My biggest fear is I screwed something up by compressing the fuel tank to get fuel up to the motor. Could I have caused to to hydro lock on fuel from that? It was turning over perfectly fine prior to doing that but wasn’t firing.
So the engine turns over by hand, but the starter is what quit working ?? Did you get the wires pinched between the engine and tranny that run down to starter?
It doesn’t turn over by hand. Sorry I see the mistake in that post and I couldn’t get it to turn by hand with glow plugs out either.
Then there is certainly something hard stopping it and a borescope will be your friend.

I've never seen a cp3 lock a motor up personally. I think you have slot bigger issues. Start pulling the motor apart
I heard of an lml doing that just recently. After pulling the heads it was determined that removing and reinstalling the y bridge had loosened some egr soot and it got in on top of several pistons.

I guess I should clarify,the motor I'm talking about would rotate either way but wouldn't rotate 360 degrees. After reading the entire thread I'm not sure what the op's engine is doing
