PTO pump issue

Believe its a permco pump not sure on the pto but both are only a year old, never been ran more than the time it takes to raise the bucket up. I had a surgery done and the truck has been sitting for about 2 months, I just had it running to make sure everything is still moving good and I can't get any pressure. Pump engages and disengages normal, sounds normal but just don't have any pressure. I tried engaging and disengaging multiple times and about every 3rd time I can get it to move very slow if I idle the engine up but thats it. Seems like its got air in the system? Never had this issue before and its not the first time the tuck has sat for a month or so, just hoping the pump didn't crap out. Also the trailer is only a year old, cylinder is completely dry.

 

I did check that as well thinking maybe somehow a line got loose and leaked out but I've got 40 gallon or more in the tank
