In the past when I've installed motors, I've never had an issue with a pump losing its prime. You have to think about what put that motor in the yard, and it could be a failed oil pump. If youdecide to get a new oil pump, you'll need to prime it. What I typically do is take some vaseline and suck it up into the pump gears (or if you can't get it to suck, disassemble the pump and put a bunch in the gear). The vaseline will dissolve in the oil once you get the car started and oil starts flowing.
Another thing to consider is that if the oil pump went bad, look at the bearings of the crank to make sure they haven't spun from being dry.
