87 renix starting problem

[87woody-atl]

Plugs are in correct firing order.

All the wires coming off the battery are brand new.

Sorry if I don't jump on the idea that's it's the flexplate, when I've pulled this motor 5 times now, and I just replaced the flexplate, my reasoning is due to the fact that the cyclinders have compression when the spark plugs are in place. Wouldn't I see this crack that is causing the flexplate to flex so bad that it's binding on something?

The weird thing in my mind set is I have all the spark plugs in place causing compression yet when I pull the cps plug, which causes the spark plugs not to spark, but still keep there compression, y is the starter turning the motor without a problem.
Could there be another sensor that is tellng the starter to stop turning

Wires in the wrong order can cause a misfire at the wrong time stalling the starter motor, but it shouldn't completely stop.

Triple check your firing order and TDC setting.
