To find it:
1. Consult your owner's manual: This is the best place to start. It should have a diagram of the fuse box showing the relay locations.
2. Locate the underhood fuse block: This is usually a rectangular box under the hood, often near the battery.
3. Look for a relay labeled "Fuel Pump" or with a symbol depicting a fuel pump (often a gas pump icon). The relay itself might be labeled, or you might need to consult a wiring diagram (available online or through a parts store).
4. If you can't find it labeled: Many diagrams available online show the fuse box layouts for 1987 Camaros. Search specifically for a wiring diagram for your year, make, model, and engine type. They are quite detailed and will show the fuel pump relay location.
Important Note: Since you're working with electrical components, disconnect the negative terminal of your battery before starting any work to prevent accidental shorts or shocks.
If you still can't locate it after checking these resources, a local mechanic or auto parts store should be able to assist you.
