Johnson v4 won't fire.

[Beakster]

Boat started up, ran strong for 10 seconds. Cut out. Won't fire. Doesn't even try. Took a plug out to look for a spark and didn't see one

Where should I start?

1980 v4. I got it started by cutting the black and yellow wires to power packs.... Any idea how I fix it properly?

Does it have a kill switch that lanyard may be pulled?
