Where is the fuel cutoff switch on a 1995 Chrysler new yorker?

There isn't a readily accessible, easily identifiable "fuel cutoff switch" like you might find on some other vehicles on a 1995 Chrysler New Yorker. Modern fuel systems rely on the ignition system to control fuel flow. Turning the key to the "off" position shuts off the fuel pump.

If you're looking for a way to quickly stop fuel flow in an emergency (e.g., fire), you would need to disconnect the fuel pump's electrical connection. This usually involves accessing the fuel pump relay or the pump itself (located in the fuel tank), both of which require significant mechanical knowledge and are not quick or easy to access. Attempting this without proper knowledge is dangerous.
