Path that i went threw from sigma wagon F07W 6g72 sohc not starting till starting again.

What happened is that one cold morning -10 degrees, it started and drove like 3 meters and engine stopped and is not starting.

When started digging online i went threw this : Testing The Power Transistor, Ignition Coil, And Crank Sensor

Did all the tests and what failed is that Power Transistor Switching Signal Output is not going out as The Power Transistor Is NOT Getting An Activation Signal from ECU

did not did all from here as i found it later on NO SPARK troubleshooting guide

so i left nothing changed under hood

took of ECU and found that it has been burned:

ECU AW 333975 board E331B991B burned
ECU AW 333975 board E331B991B burned 1
ECU AW 333975 board E331B991B burned 2
ECU AW 333975 board E331B991B burned capacitors

So after all the find i got those capacitors re welded and that burned part changed

ECU AW 333975 board E331B991B
ECU AW 333975 board E331B991B back side
ECU AW 333975 board E331B991B front side
ECU AW 333975 board E331B991B with cover

car still don't start
