No separate CDI.

No separate CDI. Where should I start checking then? I have no spark My key works so it's not the immobilizer Checked all fuses Kill switch works Fuel pump and starter both engage Any help would be much appreciated

Red light goes off as normal operation Just like the manual says Red light comes one when key in On position and the goes off and no blinking lights so I think that's not the issue

Check the coil for continuity to the ECU, and for resistance values as outlined in the workshop manual.
