Developed a crank-no start when it's wet outside

I have a 2002 chevy s-10 pickup, 4.3 V6 vortec, 4 wheel drive. ISnow, rain, even high humidity.

Things already done: cap/rotor/wires/plugs; coil; fuel pump (fuel psi between 45-55). There was an issue with the distributor being chewed up by the cam - cam gear was inspected and is supposed to be in good shape. A used distributor was installed by the local shop. Engine has 200,000 miles. I was told the timing chain is a bit stretched but there is no timing problem.

When it is running, it purrs like a kitten. Good power, smooth idle, no smoke and there is no engine codes generated by the crank-no start problem. I have power to the coil when it's not starting, fuel in the system, even have a spark out of each cylinder wire but it still won't start.

Anybody out there have any idea? I think the car is possessed!

Have you checked the crank sensor? Also, in the dark, start the engine, open the hood, and mist everything down with water to watch for sparks or arcing.

Ignition wires have been replaced by brand new and if the crank sensor was not functioning, I would get no spark from the coil into the distributor - which I am getting. I doubt that it's the crank sensor and it's definitely not the ignition wire - any other suggestion?
