Evidently the starter is working so my question is: what is in the circuit that tells the starter to disengage thinking that the car has started? It seems there is a fault in a sensor that talks to the starter. I removed the starter relay and bench tested it and it's fine. What else??

I vaguely recall reading of a similar issue that was resolved by replacement of the push button start/stop switch in the dash.

You may not be reading my replies, I shared that the battery, starter and starter relay are good, what am I ignoring??
