Where is the fuel shut off switch for a 1991 dodge shadow?

A 1991 Dodge Shadow does not have a readily accessible fuel shutoff switch like some other vehicles. There's no easily located switch in the passenger compartment or engine bay. The fuel system relies on other safety mechanisms to prevent fuel flow in a crash. To stop fuel flow, you would need to disconnect the fuel pump's electrical connection or, as a last resort, deal with the fuel pump directly (this is not recommended unless you are very experienced).
