Motor has been in use for a few years. Just quit yesterday.Was it previously working and just stopped? Or are you wiring it up for the first time? Could be the capacitor, but they also do that if you wire them wrong. i.e. if the pump is wired for 110 and you connect it to 220, or vice versa. Many of those pumps will operate on both, you have to change some wires under the cover to select which one.
Shaft is not exposed to "give it spin". Even if it was, I'd have no way to spin it without killing myself.A new cap could be the first option to try.
OR if a start switch is fitted internally, try giving it a spin as fast as possible in the proper direction and then apply power, if it runs then you pretty much know the motor is OK.
I would start there then move on to that capacitor. Your symptoms sound just like my air conditioner did last year. A trip to the parts store and a capacitor later it runs just fine. Most places which sell home appliance parts have capacitors like the one you may need. It would be a good place to start looking anyway.When replacing the cap ensure it is a Motor start rated, these are generally bi-polar electrolytic.
As to nervous about spinning it there is a slot in the rear shaft you could put a power tool on with a screwdriver bit!
OK, then we start with the capacitor.You guys and your screwdrivers.
Do you know how close that exposed shaft is to live 220VAC?
I told you, this stuff makes me nervous!
Yes, I turned the shaft to ensure the rotor is rotating freely without any apparent rubbing or excess friction.
But, no! I will not stick a screwdriver (or power tool) in there while the AC is on.
