What is an ECU and what does this part do:
An ECU is an electric scooter part that ensures that your ignition (combustion) takes place at the right time.
Behind the flywheel/cooling fin is an ignition coil and pick-up (signal generator).
This sensor signals to the ECU where the piston is located.
The ECU calculates when a spark should be generated to enable the combustion process, and transmits this signal to the ignition coil, which transmits an electric shock to the spark plug.
If the spark plug does not produce a spark, this could be due to several parts, including the spark plug and the ignition coil.
You can find out if there is a spark by unscrewing the spark plug from the cylinder head (when it is cold) and holding the threads against your cylinder using pliers while you attempt to start.
