I thought that ECU needed to see neutral to start.
ECU needs EITHER Neutral OR side-stand up - it WILL start, even in gear (i.e. no neutral indication), as long as side-stand is up.
The Touring model is different than the std (or Roadster) in that the Neutral Signal does not go directly to the Instruments (as well as the ECU, on those other models) only to the ECU.
If it won't start with side-stand raised either, you are chasing a red-herring with the neutral light indication.
The side-stand switch have to fail simultaneously if that were to be a consideration, as if it had previously been an issue, even if bike started it would have died immediately when put in gear.
(the ability to run, not just start, is interlocked by the side-stand or neutral status)
So I think fair to discount the neutral indication as being the prime mover here - and the lack of neutral indication is an effect rather than the cause.
Can you describe what else it does when you first turn on the key? (or set the Kill switch to run, after setting to kill)?
Do you hear the fuel pump prime? Do Instruments sweep?
Can you check for voltage at both sides of fuse 6?
Do you hear (or can you feel) the engine management relay 'click' when you turn Kill/Run switch on/off?
Again, different on the Touring, the Ignition Power goes directly to the Instruments BEFORE the Kill/Run switch - so the Oil indication etc is not necessarily an indication that the Ignition circuit is good - so check the Kill/Run switch and also the Engine Management Relay (and the Alarm Bypass connector)
Check the right-side bar-switch connector to main harness - make sure that is properly latched.
Some history would also be helpful - parked bike one day, went to start next, wouldn't start?
Or was there anything you did between last time it ran and now?
