Usually when there's a no spark situation the Ignition Control Module is bad.
Not always, the ECM can also go bad and cause this. I would suggest to the OP to check the fuses for the ign. There is one under the hood by the battery and one under the dash by the PB assembly. If these are good then I would check to see if you are getting voltage to the coil. Not to long ago another fellow Jeeper had an issue like this and it was the coil connecter one plug was falling out of the connecter and not making contact to the coil.

Not sure how all of this works but should the coil have 12 volts to it any time the switch is on because it does not. I guess I need to read up on how the ignition works. I understand points and condensers but not much about electonic ingition. Guess that is what I get for being old.
