You can look through the fuse plastic and see if the link is burned or use a test light / ohm meter.

Don't replace the pump until you have unplugged it and checked for power at the pump just after a cold start. ( Be sure to keep test wires away from the fan belt )

You can also apply power to the pump and see if it spins. You will get a pretty big spark when attaching a wire as it draws lots of power. Polarity matters for rotation of direction, I don't have a wiring diagram handy to check that out.
