Troubleshooting a Johnson Pump

I went to drain and winterize my Aqua Jet wash down pump today and it won't run. It isn't that old nor has been it been used heavily. The power leads are fine. The manual suggests a faulty pressure switch or faulty motor. My gut feeling is its the pressure switch. Are these prone to failure, and does anyone have any tips for testing these? Thanks for any help. Thankfully it's not urgent, I have the whole winter to figure out out!
