Is the pump chattering, basically trying to spin but isn't? If it is a venturi, try blowing in the venturi tube, that should get things spinning.
My hydor, has 3 pumps, as it is a recirc... the 2 recirc pumps sit on their sides and don't always want to start when I turn it off. I blow into the venturi tube and they start right away, every time.
Hope that helps.
