If continuity tests to zero, or close, then wiring is OK.

As jrolin1 said, you could switch the breaker with a known other breaker of the same rating and see if things stay the same. That means that your breaker is OK.

Your next test is the pump motor for an overly high starting draw; indicative of a failing motor.

If you aren't familiar with a volt-meter, no worries. Go to Radio Shack or electrical supply house or big box store. Any of their salesmen will be able to spend the two minutes it takes to get you comfortable with using it's most common features (12V, 120V, and continuity testing)
