1. A system for preventing spark-on-make in an internal combustion engine, comprising:

  • a pressure sensor adapted to detect pressure in an intake manifold and provide an output signal indicative of that pressure; and

    a controller at least indirectly connected to the pressure sensor and 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.
