I have a Yamaha Vmax ox66 150 was wondering if anyone could help me figure out why it's not getting spark to any cylinders. It sat for a long time and because it needed a fuel pump. I had bought one but just not made the time to put it on. Recently put it on and put new batteries but then it wouldn't start. I immediately thought it was because of fuel pump but changed all filters and verified that new pump was running and fuel pressure was normal. After verifying was not fuel issue I realized that no cylinders were getting spark. Also when lanyard is off I'm not getting warning alarm when I crank the motor so I believe it could possibly be with the emergency stop but wanted to see if anyone could give me any input or advice on where problem might be or where to start thank so much in advance

I would start with checking out the lanyard switch...the alarm should sound. Meter out the switch to see if it works. That is exactly what that switch does...kills the spark when the lanyard is pulled off or the button is pressed. Probably corrosion in the switch.

Pan, your reading skills are better than mine.
I thought he said it did sound the alarm when he pulled the kill switch
it should kill spark and set the alarm
bad connection in switch or bad ground wire maybeLast edited by 99yam40; 09-21-2019, 04:05 PM.

I am not positive on it sounding the alarm.
not every motor does that.
did you turn the key to start or just to on position when you tried it?
