>That will of course, drain most of the fuel out of the fuel lines - but not all.
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.
