I store the pump motor inside all winter (its a Hayward I believe). I hooked everything up yesterday and when I turned it on the pump motor hummed, but would not turn. Just wondering what I can check myself before I have to take the the thing to the shop. Thanks.

Welcome, 
We'll need more information on your equipment, brand/model, etc.
You can put all your pool and equipment info in your signature -
Go to User Control Panel, then Profile, then Edit Signature.
One of the equipment gurus will be along shortly to chime in.

Great, thanks! I am at work right now. I will add the information as soon as I get home.

see if you can turn the impeller by hand. if its frozen then the bearing have seized most likely.
Sometimes, if you can turn the shaft a turn or two by hand you can often get it unstuck, and the motor may then start normally.
Other times, giving the pump a solid bump with a 2x4 (not hard enough to dent it) will unstick the starter switch and it will then start normally.

The motor could have seized, and if so should respond to hand-turning (with power off) to break the 'stiction'.
Since you unwire it to store and reconnect it to install, I would first look to make certain that the connections are good, that the capacitor hasn't gotten disconnected, and that it is wired for the correct voltage. 120 volts on a motor wired for 240 often results in a hum.

Try replacing the starting capacitor or the centrifugal switch may not be functioning properly.
