966 MCV pump won't prime

Changed out the MCV pump and hyd filter and it doesn't want to prime up. Hitch works fine. I'm going to do the five gallon overfill in case of internal leaks. Will pulling the plug out of the orifice port on the rear of the MCV and starting it help any? I have only ran the engine 30 or 45 seconds, ran it up to about 1500rpm once, light is flashing, no manual steering, no pressure on brakes, no Joy! Any suggestions? I had only about 5% power steering before, had a brand new pump and kit so I thought it was worth a shot.
 
Did you prime the pump first with a little oil??. Ya you can pull the plug but ya had best get a couple bags of oil dry first as it makes a huge mess not counting the lost oil. Do the over fill and start the tractor and run the engine up to around 1500-2000 and TURN the steering wheel to the left and keep doing this till she primes. With a new pump she should pick wright up . Had you primed the pump first she would have picked it up wright away . Just try again she should pick up in a min or so.
