Dear CF riders. maybe somebody has an idea what else i can check, I have a 650NK, that wont start today. lights come on ok with igntion but turning to the run position there is no sound of the fuel pump engaging and there are no EFI/ ECU test light sequence showing. starter button literally does nothing, ive checked the fuses and main fuse, checked battery charge and terminals. checked connectors to fuel pump. Still instrument panel lights and navigation lights come on but will not start. Has anybody had similar problems where it wont do the F1/EFI test sequence and or no fuel pump sounds on turning the key on. all help appreciated ..  thanks ahead

There might be a relay. Not familiar with there bikes

Maybe a dead relay as Cosmo said. Also check the actual wires into the battery terminals as sometimes these are not soldered properly.

Mine wasnt used for about a month, and is now doing the exact same thing. Did you ever get around to resolve your issue,if so, care to share?
