Need help troubleshooting pump; won't spin

[madgame8]

Ok thanks for the advice. So far this is what I have tried:

1) cleaned out any debri in the strainer basket.
2) Tried to turn the impeller through the strainer basket with a screwdriver; it barely budged.

When I turn the power on, I can hear a hum and smell a burnt electrical smell. By then the circuit breaker had tripped.

Any ideas? I'm trying to narrow down whether this is a capacitor, motor, or pump issue. Any other real simple things I can do to diagnose? Thanks!

One other possiblity is that something is lodged in the impeller if it is not spinning freely or the bearings may have siezed up.

Every spring, I have to take off the strainer basket, remove the impeller and use a pliers on the motor shaft to break the motor free. (Be careful not to damage/score the shaft with the pliers.} That is how I free up my motor.
