Fuel Pump Assembly
The fuel pump on this EFI model is prone to internal motor failure or a clogged integrated filter, preventing the fuel rail from reaching the pressure threshold required for the injectors to open. Even if the pump is audible, it may fail to generate the necessary PSI to atomize fuel into the combustion chamber. Replacing the full tank-mounted assembly restores the hydraulic pressure necessary for engine ignition.

Crank Position Sensor
The Crank Position Sensor (CPS) provides the ECM with the timing data needed to trigger both the ignition coil and the fuel injectors. If the sensor fails, the ECU cannot synchronize the firing order, resulting in a 'crank but no spark' condition. This is a common failure point where the sensor loses its magnetic pick-up capability due to heat or vibration.

NGK Spark Plug
Single-cylinder high-compression engines are sensitive to spark plug fouling, especially if the machine is started and stopped frequently in cold weather without reaching full operating temperature. Carbon or fuel deposits on the electrode create a low-resistance path that prevents the high-voltage arc required to ignite the compressed air-fuel mixture.
