If the clutch switch were the problem then the starter motor wouldn't work so I doubt that it is that. It would be unusual for all three coils to fail at the same instant so I doubt that they are the problem, but it wouldn't hurt to make sure that the low tension cable connections are clean and that all the connections are good. I think that either a connection to the ECU or the ignition switch are the main suspects.
