Did you pull the headunit out (stereo)?
Yes.
If so, have you caught the cable that runs to the START button?
They are in close proximity; hence my question.
I tried to look at it but it seemed to me to be fine.
But for sure there is something disconnected since no button has light. I cannot just understand where to check
Funnily enough I've had the radio out on my aero today to put in an aerial switch. I know you've probable checked this but have you knock the shift leave out of park? If you have it won't start.
Sorry if I'm teaching you to suck eggs. Other than that you've got a lot of wiring behind the dash, have you dislodged a wire from the starter?
Yes, shift checked, it was in parking (but later I'll go again to check it).
Behind the dash there were only who whitish connectors and they were properly connected.
Meanwhile the video is uploaded (if it helps)
