* Under the hood in the underhood fuse/relay center: This is the most likely location. The fuse/relay box is usually located near the battery, often on the driver's side fender well. The relay itself will be either in the main box or possibly a smaller secondary box nearby. Your owner's manual should have a diagram showing the fuse and relay layout.
* Inside the cab, under the dash: Less common, but some S-10s might have it inside the cabin, usually near the fuse panel under the dash.
To find it, you should:
1. Consult your owner's manual: This is the best resource. It will have a diagram of the fuse and relay boxes, showing the location of the fuel pump relay.
2. Look for a diagram on the inside of the fuse box cover: Many fuse box covers have a diagram printed on the inside showing what each fuse and relay controls.
3. Use an online resource: Search online for "1993 Chevy S-10 fuel pump relay location" along with your engine size (e.g., "4.3L"). You might find images or forum posts from other S-10 owners.
Important Note: Before working with any electrical components, disconnect the negative terminal of your battery to prevent accidental shorts. If you are not comfortable working on your vehicle's electrical system, it's best to take it to a qualified mechanic.
