Water Pump issue

OK. Filled 100% with water. Turned all valves to "summer use" position. No water. Turned them back to winter position and tried to add anti freeze and nothing. The filter itself I finally got off and there was a little gunk but cleaned it all out and put it back before filling and trying to run water. Still nothing. The pump does come on and I hear it going continuously. Right now water is off, if I go out to the basement area where the pump is, I can hear it running. But nothing is happening.

Is it probably the pump at this point?

Thanks for the replies.
