A system is provided for preventing spark-on-make in an internal combustion engine, using manifold pressure information. The system includes a pressure sensor and a controller. The pressure sensor is adapted to detect pressure in an intake manifold and provide an output signal indicative of that pressure. The controller is at least indirectly connected to the pressure sensor and is adapted to delay initiation of ignition dwell in a coil by a period of time sufficient to avoid spark-on-make, in response to the output signal from the sensor. Preferably, the pressure sensor is a manifold absolute pressure (MAP) sensor. The controller preferably is implemented by suitably programming or otherwise configuring an electronic engine control unit (ECU). Also provided is a method for preventing spark-on-make in an internal combustion engine.
