2003 Yamaha 150 HP OX66: Is there a single source of power that supplies voltage to all 6 coils at the same time? I have no spark to any of the spark plugs. The engine spins strong but doesn't start. I can hear the fuel pump pressurize when the key is on, and then after some attempts to start, the smell of gas is present. I checked the lanyard circuit, the ign switch circuit, the batteries are new, I checked and cleaned all ground connections, or at least any I could find. This happened out of the clear. It has to be something common to all 6 coils. The motor ran fine for the past 12 years - this is the first problem.
