Yes, I have seen where the water pump impeller falls of the pump so no coolant can circulate. I would remove the thermostat and refill with water then start the engine you should see water flowing. To be absolutely sure I would remove the upper radiator hose and start it water should rush out if not the water pump is no good and need to be replaced. Here is a guide to help you see what you are in for when doing the job:

and what it will be like for your car (below)
Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
