2007 Chrysler Pacifica, Won't crank or start

4.0 Motor
Drove for 30 miles, parked for 3 hours, never cranked again. Drove with no
issues, no check engine lights. I have replaced starter, battery, alternator, new
ground wire, ignition actuator pin. All dash lights turn on, I hear clicking in the
relay box, I switched the relay out. I don't hear anything on the starter clicking
though. What on earth could it possibly be???
