not start after rain 850

My '94 non-t 850 wagon with about 600K miles runs great most of the time (original engine!).
But after a long soaking rain or a few days of moderate rain, she wont start. Was away and let her sit 3-4 days after the rain and she started right up, ran fine.

I always was told hard/non-start conditions in rain/damp weather meant bad distributor cap, rotor or wires. I replaced plugs a few months ago, but wires, dist cap and rotor are old. Should I just replace these or is there any other likely issue?
thanks,
mark

    The next time it won't start - in the dark - look under the hood while someone tries to start the car. You might see some sparks.

    Long shot - what shape is your air filter in? Really dirty, it might block sufficient air if it is damp.

    Interestingly, I would never suspect spark plugs to cause a problem in the rain - they never get wet at their business end!

    Give your car a treat - new ignition parts - lest it let you down in the wrong circumstance.

      Thanks - yes I think I will change the ignition parts.
