batt terminals are tight ? You used a multi tester to check all those connections and power is getting to the starter solenoid when you hit the key ? By cranking you mean the engine does not turn over ?, Do a voltage drop test from batt to starter , Your not in the matrix are you ?

Motor turns over by hand with spark plugs removed ? replacement motor is good ? Is there a solid click at the starter ?

Motor turned freely no drop in voltage no click at stater. Starter worked perfectly when I bench tested
