Fuel deactivation is activated when the engines on the over run ONLY. So if you going down hill and you take your foot off the throttle it shuts ALL injectors to save fuel which in effect stalls the engine until it detects a input from the pedal or the RPM drops below 1000rpm. This stops it stalling completely. It also is momentarily active when you accelerate then take your foot off the throttle.
IF it malfuctioned your car wouldnt start. It is controlled by the ECU. It is easily checked with opcom as it displays the status of this
