* Under the hood in the fuse box: This is the most common location. The fuse box itself is often located near the battery. Look for a relay that's clearly labeled (though the labeling might not be explicit – you may need to consult your owner's manual or a wiring diagram).
* Under the dash: Less common, but possible. Again, consult your owner's manual or a wiring diagram.
To find it definitively:
1. Consult your owner's manual: This is the best place to start. The manual will show a diagram of the fuse box and relays.
2. Use a wiring diagram: A wiring diagram specific to your 1992 Chevy S10's engine and options is essential for positive identification. You can find these online (often on sites dedicated to automotive repair information) or at a parts store.
3. Visual inspection: Once you've located the fuse boxes (there might be more than one), carefully examine the relays. Some might be labeled, and you might recognize it based on size and appearance compared to images of fuel pump relays online.
Important Note: Before working with any electrical components, disconnect the negative battery terminal to prevent accidental shorts and injury.
