For you guys that are electrical and/or pump/motor geeks........I've got a Little Giant pump that doesn't start when you give it power. If you spin the impeller just a little, it'll take off but not on it's own. Is that possibly a capacitor issue? Or is it something else? I've oiled the bearings and the shaft is free turning so it's definitely inside the motor. I'm just looking to determine if it's something simple that can be fixed or if I should just trash it.
