Car wont Start on 1993 Volvo 940

Every time we have a rainy day my car will not start. The battery is less than 1 yr old. When the sun comes out a day later the car will start right up and drive for weeks at a time and then when it rains again the car will not start.

What are the symptoms? Does the engine spin when turning the key?

Have you checked the distributor cap? Is it cracked, allowing moisture in? I had that happen once, and the car wouldn't start.
