The most likely cause is water in the distributor like Gary said, it's quite common after spraying the engine down. Especially if the engine was warm before you sprayed it. Pop the distributor cap off and look inside it and the distibutor for water or condensation. If you find any blow air though it until the moisture is gone or just let it air dry. When you try and start it if it bucks like a misfire but tries to start you have spark jump in the cap due to the water. Another cause could be cracks in the plug and coil wires. Electric Current will always seek the path of least resistance to ground which will be through the cracks along the wet outsides to ground. Dry the wire would not give you any problems but increase the moisture content and it creates a short. I've also seen the coil dump it's voltage along a wet coil. If you find and water in the distributor look around the base of it for any openings. Bosch distributors sometimes have an opening on the side covered by a plastic plug, your's may be missing.

No telling why the plug is missing. You can look for another or take a piece of duct tape and put it on the out side of the housing. Another way water can get in is around the vaccum canister and where the condenser wire enters the housing.

The tape will help keep out water and road debris but won't help you current situation. How long has it been since you hosed the engine down? Did you check for spark with a plug wire or from the coil wire? Just because the coil fires does not mean the spark will make it to the plugs.

If it has been 4 days now the distributor would be dry. The condensation only last a few hours ay most. Check the see if you knocked any wires off. First place to look would be the wire on the negative side of the coil and the wire on the distributors condenser. Also pull on if the spark plug wires off the spark plug and see if you get a spark while someone else is starting the car. Be careful because the spark can shock you, better to use insulated pliers to hold the wire.
