To find it, you'll need to check these common areas:
* Under the hood in the fuse box: This is the most likely location. The fuse box is usually located near the battery, often under a cover. Look inside for a relay that's labeled "Fuel Pump" or that has a diagram showing a fuel pump symbol. You might need to consult your owner's manual (if you have it) or a wiring diagram specifically for your truck's year and model to identify the correct relay.
* Under the dash: While less common for the fuel pump relay itself, some components related to fuel delivery might have relays located under the dash fuse panel. Again, a wiring diagram would be helpful.
* Inside the cab, near the steering column: Some vehicles housed relays in this location, but it's less likely for the fuel pump relay in a 1988 S10.
The best approach:
1. Consult your owner's manual: If you have the original owner's manual, it should provide a fuse and relay diagram.
2. Use a wiring diagram: Find a wiring diagram specific to your 1988 Chevy S10 4.3L. Online resources (like repair manuals websites) or automotive parts stores might offer these. The diagram will pinpoint the relay's location.
3. Look carefully in the under-hood fuse box: This is the most probable location. Start by visually inspecting the relays and their labels.
Without specific information about your S10's options and trim level, pinpointing the exact location is difficult. Using the steps above will significantly improve your chances of locating the fuel pump relay.
