Is there a fuel pump reset switch for 1992 Chevy blazer s 10?

No, there isn't a dedicated "fuel pump reset switch" in a 1992 Chevy Blazer S-10 (or most vehicles, for that matter). The fuel pump is controlled by the PCM (Powertrain Control Module) and various safety sensors. If the fuel pump isn't working, it's not a matter of resetting a switch; it points to a more serious problem.

Possible causes of a non-functioning fuel pump include:

* Blown fuse: Check your fuse box for a blown fuel pump fuse.

* Relay failure: The fuel pump relay might be faulty. This is a common point of failure.

* Fuel pump itself: The pump might have failed.

* Wiring issues: Damaged or corroded wiring can prevent power from reaching the pump.

* PCM problem: While less likely, a faulty PCM can also prevent the pump from operating.

* Inertia switch: Some vehicles have an inertia switch (a safety device that cuts power to the fuel pump in a collision). Check to see if your Blazer has one and if it's tripped. It's typically located under the dash or in the engine compartment.

To diagnose the problem, you'll need to test the fuse, relay, and wiring. A multimeter is a helpful tool for this. If you're not comfortable performing these checks yourself, it's best to take your Blazer to a qualified mechanic.
