no crank no start

Hey all, My 2004 Liberty Gas A/T stopped working out of the blue one morning. It started for half a second then died, wouldn't even crank anymore. Then I tried again a few hours later and then it would sometime crank (but no start) or not crank at all. I tried pulling out a potential code error...

I have a 2004 Jeep Liberty, the starter is new but the car does not crank, we've changed the battery, the ignition switch, some of the relays and so many parts and the car still does not crank. It only cranks when I Bypass the Starter Relay Fuse
