Hello my friends I have problem with my Yamaha there is no spark on cyl 2&3...
As I read carefully all the posts here I try to follow but I stuck...
--Red wires on both gives me 12V
--Orange one it is in continuity no short to the chasis
--Grey one same
---what confuses me is that with out the ecu i have continuity between orange and grey (i think they can't be in communication) also i can see that there is communication between red wires and orange and red wires and grey..
---Doing the test at code 31 there is nothing...the light at the dashboard blinks 5 times no spark..at code 30 there is a spark..
---primary secondary resistance on both are in the specification...
Can you help please?
