A technique for detecting misfire due to a fault in the secondary of an automotive ignition system compares the ignition signal developed by the ignition coil, preferably the primary winding thereof, to reference signals. Abnormal results which occur at predetermined times subsequent to the initiation of the ignition signal indicate short circuit and/or open circuit conditions in the ignition system's secondary. In response to such fault conditions, fuel is preferably shut off to the cylinder associated with the misfire.
