On a v8 engine, if you mix up the sparks it's possible to cause a spark at about 90 degrees after tdc, which will cause a backfire through the exhaust, or at 90 degrees before tdc, which will cause that cylinder to try and turn the engine backwards and cause serious damage. Or at 180 before tdc, and backfire through the intake and light your carburetor on fire. Fun times.
On our 4-cylinder engines, mixed up wires can do the following:
1: fire correctly, at about 10 btdc on the compression stroke.
2: fire at 10 btdc on the exhaust stroke. This could cause a backfire through the exhaust, but won't cause any damage.
3: fire at 170 after tdc, near the bottom of the intake stroke. At this point, there's probably not enough compression for gas to light, if it did ignite it would backfire through the intake--the way our fuel injection system is designed, that probably wouldn't cause any damage. If the gas actually ignites or is still burning after the intake valve closes, this will put some pretty extreme stress on your rod bearings and could cause serious damage. And it would stop your engine hard.
(4) fire at 170 degrees after tdc, at the bottom of the power stroke. This could backfire out the exhaust, but won't cause any damage.
None of these situations will do any harm to your ignition system.
Most likely your problem is water somewhere it doesn't belong, like inside your distributor cap or in the wiring to the distributor cap. It will dry out in a couple of days. If you're impatient, you can go through the steps like you would for any no-start situation: test for spark, test for fuel, test for compression. Your problem is probably spark, but you could have got water into the fuel pump wiring too, or knocked something loose. If you don't have spark, test everything in the circuit. I would pay particular attention to the wiring connectors at the distributor and at the coil.
