Will either be the start capacitor (in the box on top of the motor) or something binding the impeller or potentially both. There is a fan cowling on the rear end of the pump try this; - Turn the power off - Remove the cowling - See if the fan allows you to spin freely/easily the pump BE SURE nothing could become entangled in the fan - Turn pump back on - If it starts, probably something on the impeller side - If it doesn't but will start with a little turn of the fan probably the capacitor. Get a new one from Jaycar or RS components Remember to put the cowling back on safely.
