I just had this exact problem. Wouldn't start or took 15 trys to start, but then ran smoothly. Sometimes a little rough starting on dry days, but pretty much hard starting after rain. I was thinking water in my tank/bad gas, but shooting some starter fluid in my intake didn't give me the initial blast at start up... that certainly indicated that it was electrical...
...but the next day the vehicle stalled in the middle lane of a three lane street, wouldn't restart. After pushing it to the curb, I got to the point where I was checking the wire from the coil to the distributor cap. Two thirds of the wire lifted right out. This wire was in 2 pieces! Amazing that it had been running at all, with this one wire burned down to a whisper, before it broke completely. There were signs of heat/elec damage to the wire also at a point an inch away on this wire.
Replacing the wires is absolutely the first thing to try. It's cheap and easy to do, and it should be done (or the wires inspected/tested) routinely anyway. The coil-to-distributor coil gets more engine heat and more use than any of the indiv spark plug wires and hence wears much faster.
I am betting this wire is much more likely your problem than a coil failure. Good Luck!

SOURCE: When it rains, my car dies.
it sounds like the computer is getting wet; on a clear dry day, wash the car and check for any leaks up around the windshield before drying it off especially if the water coming in on the passenger side behind the glove box because that is where your computer is located

these vehicles get moisture in the distributor cap. replace those with GM ONLY parts. When you go to install the cap, put a bead of wheel bearing grease on the outside of the cap only where it seals to the distributor base. This will keep out the moisture which causes corrosion.

I would check your spark plug wires, when it's been dry out, start the car and with a spray bottle, spray the plug wires and see if there is any difference, also the coil wire. The smell is most likely from the catalytic converter. Any check engine light?
