If the battery is at full charge (12.6V), the next thing to check is the battery cable connections and connectors. ( BOTH ends.)

Remove/clean thoroughly ends of the cables and the connections they make.

Make sure all grounds (battery, alternator, engine (to chassis) are clean and wrench tight, NOT hand tight.

Be sure the drive belt(s) are tight and not slipping and that the alternator is putting out proper carge.

If after doing this maintenance the engine still does not turn over, do an ignition system check (perhaps something has come loose).

Note: it's not healthy for the wallet if you start throwing parts at a problem in hopes of fixing it.

Get a proper diagnosis first.
