How do you prime the oil pump?

Since I have a roller cam, I prefilled the filter, just pulled the fuse from my electric fuel pump turned the car over for about 30 seconds and my gauge went up to 60, put the fuse back in an started it up. Should be enough lube for 30 seconds.
You could also remove the coil wire I guess. I'm sure someoe will say that's wrong but it worked for me. Thats what most car dealers do when they replace an engine, So I heard.
