Where is fuel pump cutoff switch located on 98 Chevy s10?

There isn't a readily accessible, easily found fuel pump cutoff switch on a 1998 Chevy S10 as standard equipment from the factory. Unlike some vehicles, General Motors didn't include this as a standard feature in that model year. Any such switch would have been added aftermarket.

If you're looking for a fuel pump cutoff, you would need to check:

* Under the hood: Look around the fuse box and relay area. An aftermarket switch might be mounted there.

* In the cabin: Some people install them near the driver's side or under the dash. This is less common but possible.

* Wiring diagram: Consult a wiring diagram for your specific 1998 Chevy S10 to see if any such switch is wired into the system, although it's unlikely.

If you can't find a switch, the fuel pump is controlled primarily by the vehicle's computer system and safety interlocks. Turning the ignition off is the primary way to cut off the fuel pump's power.
