Three things could be the problem....motor and veins are gummed up, not letting veins slide out like they need to to catch the air. Output shaft on rotor is broken.( throw the wrench away) . Rotor has worn into motor end plate until end plate metal has embedded into rotor making a spot on the rotor that digs into the end plate not letting it get spinning. Two of these can be repared with no parts, just take the wrench apart and check.
