2002 Chevrolet S-10 Blazer won't start in rainy weather

2002 blazer wene it israining wont startor hard to start it tunes over well not start

Are you getting a CEL when it is running?
I suspect a problem with the engine not getting spark in high humidity conditions. Could be spark plugs, spark plug wires, and/or coil(s).
How many miles on your vehicle?
Which engine?
Which transmission?
When were the spark plugs last changed?

Usually s[ark plug wires and/or distributor cap ate the first things affected by rain.
