Starting in bad weather problems
The last week new england got hammered by wet sloppy storms and my blazer would not start. It would crank and it would not catch. I checked the fuel pressure and it was at 65 psi and than I tried to put starter fluid into the throttle body and it would still not start. It would try to turn over but would not and after I turned the key back you could hear the engine cycle backwards and gray smoke came out of the air intake. Two days after all the storms after everything dried out it started fine and runs fine. So my question is how do I address the problem. Do I just pull out a squirt gun and start spraying anything electrical or are there certain things I should check?

It definitely sounds like you have an ignition/timing issue.
You can remove the ICM and the coil to have them tested at most autoparts stores. All depends on which ones you have close and if the employees know how to do it.

I have the same problem with mine. If I start it during the rain, it will be ok. If I don't run it for a day or two of rainy weather, it won't start for a day or so. I've been told it was a sensor in the distributor. Mine has an Enhanced Distributor system if that helps any. Were you able to check the components listed by swartlkk? It's caused a lot of problems and led to me changing several parts to no avail.

Since the problem occurs in cold wet weather it is most likely a spark issue rather then fuel.
The most common causes on these trucks are bad plug wires, condensation inside the distributer due to a plugged vent hole and a failing ignition control module.
A failing ignition control module is often affected by temperature. Working just fine in good weather but in heat or cold can fail. Most auto parts stores have the equipment to test them if not someone who actually knows how.
