Why does any car crank but not turn over. Plugs, timing, battery, fuel, whatever. Start where the ignition is. If that's alright, see if it's getting gas. You should smell gasoline while you pump the throttle.
If the engine is "cranking" then it is "turning over". Please be more specific.
generally , cranking an engine is done with igniton where turning is done by hand with the ignition off so as it will not start
Check the coil pack, if not that check plug wires.

Well, voltage wise, you have a lot going on when your are cranking over the engine, so some flutter, or shake is normal.
IF TURNING OVER BUT NO START TRY CRANK SENSOR There is no spartk.

what are you Cold Cranking Amps on your battery? perhaps your battery is not strong enough, if that's not the case something with the battery wiring i suppose as long as your starting is turning it should be a battery issue.
