You need to check the basics. First make sure the ECU is powered on when the ignition is switched on. You can check this by listening in the engine compartment. You should hear the idle control valve (ICV) humming. If not that means the ECU has no power or is completely dead.

Next, if the ECU is indeed alive, you need to check if you have fuel.
If you have no spark, maybe you have no fuel either. In this case it would point to a failing sensor (maybe). The ECU won't allow any spark or fuel if it doesn't get proper signals from both flywheel sensors at startup. No spark no fuel is typical of a failing sensor or a failure of the IC inside the ECU that is used to format these sensor signals for the processor.
