Ignition Coil Assembly
The ignition coil acts as a step-up transformer converting low-voltage pulses into the high-voltage discharge necessary for combustion. In portable generators, high-frequency mechanical vibrations can cause fatigue in the secondary windings, leading to internal short-circuiting or a complete break in the copper wire, resulting in a total loss of spark.

Crankshaft Position Sensor
The EFI system requires a magnetic synchronization signal from the crankshaft to determine the precise moment for the ECU to trigger the ignition pulse. If the internal Hall Effect sensor or magnetic transducer fails due to heat soak or debris on the flywheel, the ECU fails to register engine rotation and inhibits spark delivery as a safety and operational protocol.

Resistor Spark Plug
The spark plug is the final stage of the ignition circuit where electrical energy must bridge an air gap. Thermal shock or carbon fouling can cause the ceramic insulator to develop micro-cracks, allowing the high-voltage current to bleed off to the ground shell internally rather than jumping the electrode gap, effectively killing the spark.
