I have a boss5.
I had problems with my pump. No bigey. It pushed out the check ball holder for the pump. I checked all the lube points 1/2 were not getting oil. I cleaned all of them. I never could get the top 3 points working correctly with the rest of the system. I removed them from the auto system. I oil them manually now.
As far as the original pump. You can give it a shot manually as long as it is at the bottom or part way down the travel of stroke. If its at the top the stroke you will have to wait for the motor to move it down.
Do check all of the points for oil. The only way to do this properly is to disassemble clean and hook the oiler up to the parts as they sit on the floor. Each meter valve has its own filter I should have bought new ones but I just cleaned the filters and used lots of shop air to remove any debris.
Hope this helps
