ez-
the pump might be airlocked.
I've seen it before and I've jacked up the front end and turned the wheel from lock to lock to move the fluid through to clear out the air. It worked for me every time.
That is what I did but it doesn't seem to move any fluid I will try again tomorrow.
Congrats
What's with the tomorrow? Grab a flashlight and let's get to it
Might be a silly question but is the PS pump rotating in the same direction as it was on the previous engine? Don't ask me about a particular Cod boat that had an engine swap done and needed all the hydraulic pumps changed over to opposite rotation by 06:00 the next morning
After all this swap I get stuck with something as stupid as this
