What condition is likely when both CMP are not responding on a composite engine?

The situation where both Cylinder Misfire Position (CMP) sensors are non-responsive on a composite engine likely leads to a "no start" condition. This is because CMP sensors are critical in determining the correct timing for the ignition and fuel injection processes in an engine. If both sensors fail, the engine's control module may not receive the necessary information to coordinate these processes effectively.

In this scenario, without accurate data from the CMP sensors, the engine control unit (ECU) cannot calculate the proper timing for fuel delivery and spark generation. Consequently, the engine fails to fire and starts, leading to the inability to start the engine altogether.

While rough idle and start and stall scenarios could potentially involve other faults or incorrect sensor readings, they are not directly linked to both CMP sensors being unresponsive. A rough idle typically results from issues that still allow the car to run, while start and stall situations often imply temporary ignition or fuel issues after the initial start. Therefore, the most appropriate outcome when both CMP sensors are not responding is indeed a "no start" condition.
