HELP *Turbo Action Shifter Cable Adjustment*

So no matter how I adjusted the shift able, I could not get it to operate correctly.
So, I disconnected the shift cable and manually operated the lever through all the gears and tested it. It starts in P and N. But still when in N if I rotate the rear wheels for or aft, and then place the shift lever in park and try to start it, nothing happens, until I rotate the rear tires for or aft until it stops. Then it will start.
I think at this point my shift cable/adjustment is no longer the problem. Any ideas where to start next?
