LOL... no. No need for the engine to be running... you just need to have the pedal on the floor. The key doesn't even need to be turned on. This is also a good time to use a flashlight on the back of the IP, and make sure the throttle linkage is going to the stop with the pedal all the way down.

Well, thanks, that's a relief.........somehow I figured you'd need vacuum from the pump.

I'm definitely going to reset the '86 SDL........these massive flares are disturbing........
