Your LED may be lying, also. If you wired it to check for power, there's a good chance that it is. Most injection systems pulse/switch the ground side of the circuit (ecm input), with a constant power feed, often from some kind of distribution center.
If you turn the engine off, you will loose p/s. But I believe you'll get a pump or two of power brakes with the engine off. After that, it'll be a very hard pedal.
