Need Help! Motor turns....won't start

Thanks for letting us know the resolution. Usually when an engine won't fire, it is either "no spark" or "no fuel". The first you can easily check with an in-line spark tester, the latter with starting fluid. If still won't, probably something in the camshaft drive or distributor. In your slant six, those could be from a broken plastic distributor gear or a worn timing chain jumped teeth.

My Chrysler 2.4L stumped me until I found "camshaft not turning", due to failed bearings in the belt drive (twice). The first time, I had a good clue since it sounded like ball bearings rattling in a pan just before the engine died (3K miles after 36K mi warranty), second time (100K later) it died quietly (on elevated freeway) but I thought "that again?". You will get to know your engines features and faults.
