Good point, John.
Nice save by the way. Indeed shows that whichever way you have of turning off the engine, I think it should be what you normally do - so in a time compressed emergency, you don't have to think about it - and it should be something quick and simple. At that time you had the EC2 before the Snubbers (BS) which means it had the sneak circuit - which means turning off the EC2 would not turn off the injectors - but, with the EC2 WS (with Snubbers) turning off the power to it will now do the job.
How long did it take to start you heart beating after you got it out of your throat ?{:>)

Not very much at all, I'd say, Ed. How much fuel do we inject during three or four revolutions? 1/2 cup?
I think that what you achieve by turning off the pumps is reduction in pressure, not removal of fuel.
My sequence is pumps, injectors, coils, master.
By the way, I once (stupidly) started the engine in the hanger (to show my wife how the engine sounded). I think this was my second or third engine start when things weren't fully tied down and I didn't know my way around the cockpit. As Murphy would have it the throttle stuck 1/2 open. The brakes weren't holding, my wife ducked as the wing came toward her and I found myself heading across the large hangar toward a very pretty Velocity. I hit the master - she kept running. Hit the EC2 off. Kept running. Finally I turned he injector, coil and fuel pumps all off with one slap of my hand and got her stopped 2 feet from the Velo. I broke one of the switches I hit it so hard. I probably only moved 8 feet in 5 seconds, but it was a scary moment. One thing I learned from that (other than don't start engines in hangars :) was to learn my way around the cockpit until I could find things quickly by instinct. I actually practiced in the dark.
See! Rusty isn't the only contender for the "Stupid Rotary Tricks" award.
