Help - '08 YZ450F no spark after sitting for 1.5 years

Hi wonder if anyone can help - after pulling the bike out after sitting for 1.5 years, I'm not getting any spark, checked 2 plugs, disconnected kill switch no spark .. not sure what to check next? Any advise? Thanks ... ! - Joe.

Check and clean all the wiring contacts at each connector to begin with.

yes, cleaned and inspected connections, they are good.

Then perform the resistance checks in the manual as your next step.
