Hi,
I suspect you have an issue with the shift position switch. Please see the attached.
Try moving the shifter to N and see if it starts normally. By you putting power to the starter, you are bypassing the shift position switch. This switch will prevent the engine from starting because it doesn't know if you are in P or N.
I included the adjustment procedure for the switch but if there is any doubt, I would just replace it.
Let me know what you find and we can go from there.
