Need Help Fz6 s2 immobilizer issue?

Hi everyone,

I'm seeking some advice regarding my Yamaha FZ6 S2, which refuses to start. After the winter break, I unfortunately couldn't use a trickle charger for my bike as there was no power available in the garage (though it's sorted now). Since then, I've ridden it a few times (3) without any issues. However, I did notice that the immobilizer light was flashing while riding, and it didn't flash when the engine was off, which struck me as odd.

Currently, the bike doesn't start at all. When I turn the key, the temperature display flashes 'Hi', and there are no error codes. I can't enter diagnostic mode either. Also, I don't hear the fuel pump priming when I switch the key. I already tried the master key (the red one) but no luck there...

I suspect there might be an issue with the immobilizer, but I've only had the bike for one season, and it's my first one, so I'm reaching out to you all for advice.

Any insights or suggestions would be greatly appreciated. Thanks in advance!

Best regards,
Bryan

Are you sure your battery is fully charged, it might be just battery issue.
Or it might be wiring bad connection issue. Check wiring harness, which goes to immo.

I am sure the battery is fully charged, I am not sure about the wiring and harness that goes to the immobilizer (I did take out the battery) so it might be the issue thank you! I'll check it and keep you updated

Update: went to the shop to get readings on the battery and that is not the issue the battery is fine... So I am out of ideas on saturday my bike is going to the mechanic my hopes are on him. Thanks for all the suggestions and help!!
