* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery. The relay itself may be labeled, or you may need to consult your owner's manual or a wiring diagram to identify it.
* Inside the passenger compartment fuse box (under the dash): Less common, but possible.
To find it:
1. Consult your owner's manual: This is the best place to start. The manual should have a diagram of the fuse box(es) showing the location of the fuel pump relay.
2. Look for a fuse box diagram: If you don't have the manual, you can often find a diagram online by searching for "1985 Chevy S-10 fuse box diagram." These diagrams will show the location of relays and fuses.
3. Visual inspection: Once you've located the fuse box(es), carefully inspect the relays. Some relays might have labels indicating their function.
4. Use a multimeter (advanced): If you can't find it visually, you can use a multimeter to test the relays for continuity. This is more advanced and requires some electrical knowledge.
Remember to disconnect the negative battery terminal before working on any electrical components in your vehicle. This will help prevent accidental shorts and damage.
