explorer power steering noise after sitting

[Dfroman]

Hello,
My Bronco has been sitting for a couple of months (life in the way of enjoying it) I just started it and the power steering pump is making noise with just the engine running. turning the wheel makes it worse as does pressing the brakes. I have hydro assist.
a few months ago I swapped a new reservoir in (stainless steel which I cleaned well)
The hoses have a lot of vibration, not sure if they had it before, but now I am looking at everything.
Checking with the group before I start throwing parts at it. the confusion for me is that there was zero issue and now it seems like the pump is junk.
I do have a smaller pulley on the pump to increase the pressure. (providing as much info as possible)
thank you

Sounds like air in system, mine did that, had a little tiny leak in a hose fitting.

Maybe low on fluid.

I will do the air removal process. Fluid level is good, however I took that cap off while running and the
fluid does not seem to be moving?

Yeah I would not take cap off running or youll end up with it everywhere. Not moving because steering not moving. Touch steering, and fluid will fly out the top. Don't ask how I know.
