I'm embarassed to admit that you are correct and for the first time, sometime before this incident, I had turned the fuel valve to the off position. I turned the fuel on a few minutes ago an the pump clicked normally and it fired right up! I'm a big dummy! If the fuel pump clicks at high speed again, I suppose I might be able to remember the cause?
I usually ride my smaller Kawasaki around town and it has one of those vacuum operated fuel valves that shut off when the vacuum goes away so I never think about the fuel valve. Oh well, humbled again!
