Almost every 206 I get into has the boost pump breakers pulled when I get in it. Old habits die hard, I guess. And every checklist I've seen checks the throttle before the battery is turned on, but often a big red placard on the panel saying:CHECK THROTTLE CLOSED BEFORE ENGAGING STARTER. I've had my hand slapped for checking the throttle one last time by opening it with battery and boost pumps on. Not following the checklist!
I prefer the old way because if you leave the boost pump breakers in with the fuel valve on: dead battery if you leave it too long. The left boost pump will run with the fuel valve on and the battery off.
