It sounds like you need to prime the pump, yes. Since the pump is already installed, I'm going to give you the cheater's method for priming it. Take off your brake booster nozzle on the back of your intake manifold, and bolt it in place of your oil pressure sensor. Use a pump and pump oil through that nozzle - pump a lot of it in there. Put everything back how it was and crank it - you should have oil pressure then!

If you ran the car with no oiling you have bigger problems than an un primed pump now.

^^^ luckly i just filled it with oil when we attempted to start it so everything should be ok and i think i cought it before it was to late.

So if the oil pump is not primed it will not pump oil at all?

It should work. Before putting the timing belt on, I usually spin the oil pump with a drill until there's oil pressure.
