Buick Lesabre Engine Problem

My car backfired and stalled driving on the highway. wouldnt restart. turns out a spark plug was broken in half. after replacing it the firing order was messed up.. and battery was jumped and misfired somewhere and a puff of smoke.. now it only clicks when trying to start... even while being jumped.. spark plug wire is faulty ,, i 'm worried the engines locked.. without a machine to hook it up to how can i tell what is the issue

It sounds like it jumped timing. See if you can turn the engine either direction by placing a large ratchet or breaker bar and socket on the crank shaft (front of engine). Let me know what you find. Also, let me know where the plug broke.
