Where is the emergency fuel kill switch on a 1994 Chevy S-10?

There's no single, universally located "emergency fuel kill switch" on a 1994 Chevy S-10 (or most vehicles for that matter). Older vehicles generally don't have this feature as standard equipment. Any such switch would be an aftermarket addition installed by a previous owner.

To find a potential aftermarket fuel kill switch, you'd need to:

* Check common hiding places: Look under the dash, in the engine compartment (possibly near the fuel pump relay or fuel lines), or even in the glove compartment.

* Look for unusual wiring: Trace any wires that look out of place or aren't clearly part of the factory wiring harness. These could lead to a hidden switch.

* Consult any previous owner documentation: If you have any service records or modifications listed, they might indicate the location.

If you can't find a switch, it's highly probable that your 1994 Chevy S-10 doesn't have one. In a true emergency involving a fuel leak or fire, your best course of action would be to disconnect the battery's negative terminal to cut power to the fuel pump and electrical system. Be extremely cautious when doing this, and only do so if you are in a safe situation and can handle the electrical connections.
