03 Stratus RT 3.0L (mitsu)- Dies after removing spark plug wire

Dodge
Stratus RT
3.0L Mitsubishi
170K mi.
My car has been idling rough so I changed out my spark plugs. I found in doing that that my fuel injector o-rings were worn out and cracked, so I replaced those and the car still idled rough, leading me to think that my spark plug wires were worn out.
I tested this by starting the car, and while running pulled the spark plug wire off the distributor cap to see how the car responded - if it sputtered harder, that plug was good, if it stayed the same - that plug/wire combo was toast.
I pulled the first wire, no troubles, car sputtered a little, I replaced the cable and it worked. The second one, same thing. but the third one, I pulled and it sparked the tar out of me when I tried to put it back on and then the engine died. I replaced the wire and went to start the car - it would not turn over, it sounded like the starter was engaging, but the engine was not turning.
I have replaced all the wires on that bank and tried to start it, same result.
I am at a loss. Did I fry the distributor cap? the distributor itself?
Any help is much appreciated.
Thanks,
Alyx

If the engine doesn't crank, you need to troubleshoot the starting system.
When your dealing with secondary ignition systems, the one thing that you never do is remove a spark plug wire and let it hang out in nothingness. You need to ground the plug wire, so the high secondary voltage can get to ground. If you don't do that, the high secondary voltage is going try and find a path to ground by either burning a hole through the coil or whatever way possible it can find a ground inside the distributor possibly frying solid state components inside the distributor.
If you want to disable cylinders, the best way is to unplug injectors if possible. If you can't get to the injector connectors, Use an inline spark tester that you can easily ground with a test light that is connected to battery neg. You can also slip short pieces of vacuum hose between the plug wires and terminals that you can ground with a test lamp. Those tricks will not only save you from destroying things, but save you from the pain of 40 K volts running through your body.

Thanks for the info - Just to clarify, the car cranks, but does not turn over - it is trying to start but it seems as though the plugs are not sparking.

Does it have spark while cranking? Use an adjustable spark tester. Should be able to easily jump a 3/4 inch gap.
