Jluff, I would venture to say rotation is correct, as it wouldn't build any pressure if it wasn't. But one way to tell also, is by listening. if it is out it will make god awful noises. Had that same exact issue last week on a job. Try turning in up slow all the way and coming out 2 turns. Get the car to build pressure and get off the buffers. I think my car was racked a bit, and my leveling speed was to low to get it out of the bind it was in. Once I did the two turn up slow adjustment and car was off buffers, adjusted the up slow out until my leveling speed was correct.
My issue occurred after a motor and pump replacement. At first my rotation was backwards. Once I fixed that, the elevator acted just as you say.

My static pressure seems to be around 120psi. When motor pumps I can get it to about 170ish psi . 180 psi is my empty car working pressure The motor sounds normal. The car is in the pit so I can’t check the stop switch. But the Saftey circuit being open and the drive and fault contactor not coming on with out the jumper is weird. I didn’t touch any stop switches besides the one on controller. I will be back there Tommorow and hopefully I can move the car with enough pressure built up from up slow adj .. I will also change the up leveling adj. I have spares

Even when I shut off valve going to shaftway it doesn’t build pressure. Stays around 170psi Is it possible the valve body was the original problem that caused the bad motor.
