Fuel System Shutoff Feature
WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The FP module is controlled by the PCM. Electrical power to the FP module is provided through the IFS switch that will de-energize the fuel delivery secondary circuit in the event of a moderate to severe collision. The IFS switch is a safety device, located under the LR quarter trim panel. Should the vehicle shut off after a collision due to this feature, restart the vehicle by first turning the ignition OFF, push the reset button on the IFS switch, then turn the ignition to the ON position.
