The fuel cutoff switch on a Chrysler Pacifica is
not a readily accessible, easily located switch like some older vehicles. Modern vehicles, including the Chrysler Pacifica, don't typically have a readily available manual fuel shutoff switch for safety and security reasons. The fuel system is controlled electronically and shuts down automatically in the event of a crash.
If you're looking to disable the fuel system in an emergency, the best approach is to disconnect the negative (-) terminal from the battery. This will cut power to all systems, including the fuel pump.
