Mopar electronic conversion fires 4 cylinder only

So...just about everything is covered here. The answer may lie in the improbable. This situation occuring is almost impossible on its own. However, given the human factor it could easily be duplicated. That would mean you would have to cause it on purpose. Do you maybe have some friends (or fiends) who could have say altered the cap by maybe taking the contacts out for one side. Anyone with a little knowledge and some imagination could pull this off.

And now that I have concieved of this, I know just the victim i will try it on. Then I will refer him to this thread if he can't figure it out.
