94 Chevy pickup 350 motor. Cooling system won't circulate. No sign of leak and I took out the thermostat. What could the problem be?

GM uses a pump pressed on a shaft which never comes off. I have herd tell of the pump fins wearing off to the point that it doesn't pump but this would be an extremely rare event. The pump is only a few years old.

Backflush the engine block and flush the radiator. All I can do is make suggestions, I can't see anything from here. If you don't like my answer, post the question again and I will leave you alone.
