anyone ever hear of an oil pump seizing up

I'm currently resurrecting a 91 topaz with 48k miles that was wrecked and has sat since 2004. One of my many concerns is the oil pump sucking the sludge the oil turned into up into it causing poor or no oil condition when put into service. Decided this morning I was going to drop the pan to clean, inspect and replace what is needed. I was considering pulling the distributor so I could connect an old distributor shaft to my drill to engage the oil pump without starting the car to avoid any initial internal start up damage from not being lubricated for so long and to verify it was still working. Below is a discussion about oil pump priming on fords after a new pump was installed. Figured the lack of prime would cause the rest of the engine problems before the pump but if priming was done backwards long enough or at all it might be able to cause it to sieze. Neither my haynes manual nor autozone's online repair guide tell you which way to rotate it. autozone only advises that the 2.3 liter oil pump be primed. If I didn't already have the valve cover off like I do then you can bet I wouldn't take it off after dropping the pan to visually verify constant oil flow to the top of the engine unless I had to, especially if your model has an oil pressure gauge. Mine doesn't, only lights and I dont trust sensors that can be faulty as much as my eyes. Air might also be able to cause the pressure to appear higher than it is. Ran across that with hydraulic systems that hadn't been purged after repairs had been made. http://www.network54.com/Forum/74182/thread/1290972492/Oil+pump+priming+problem.
