When a motor has sat without oil in or very little oil. The oil pump empties and is very hard to get primed again.
There are some tools that you can attach to a drill to prime the pump. However, it is just as easy to remove all the spark plugs and crank the engine over until it has pressure.
I had one V-8 motor take several minutes of cranking to get the oil pressure to build up.
Try it out and see if it works. The big thing is cranking it over much longer than you think you need to. It takes some time.
