What are you calling the recovery? The HPOP supply tank?
So, It won’t start, you hooked up scanner and it shows no RPMs?

I figured out the issue was not building oil pressure. The gear was a little cocked the bolt was tight. I loosened the bolt checked gear and tightened it up and fitted right up. Now time to put the melling high flow Lpop on.

You wrote No RPM.
Make sure grooves and burrs did not occur as a result.
Make sure you torqueto spec that bolt and the thick washer is there.
