On your video on YouTube one of your checks was to use a multi meter set on DC to check the ignition coil leads and with the engine Not raining and power on the reading should be zero, you never addressed what is happening if you have a low power reading in that configuration, Approximately 3 to 4 volts.

Hello,

If you have a direct ignition system when checking the wires at ignition coils with the ignition on engine not running you should have 12 volts on the green wire and the brown wire is your ground, And the third wire is 5 an volt reference. I'm attaching a wiring diagram and highlighted the power and ground wire.
Please let us know if this information was helped and if you found the problem.

Thank you
