To find it, you will need to:
1. Locate the underhood fuse block: This is usually a large black box near the battery, often on the driver's side of the engine compartment.
2. Consult a wiring diagram: This will show you which relay is responsible for the fuel pump. You can find these online (search for "1997 Firebird V6 wiring diagram" or check a repair manual). The diagram will typically show the relay's position and number within the fuse box.
3. Look for markings: Once you have the relay number, carefully examine the fuse block. The relays are often numbered and may have some small text identifying their function, though this isn't guaranteed. They are usually square or rectangular and are easily swapped in and out.
Important Note: Always disconnect the negative terminal of your battery before working on electrical components to prevent accidental short circuits.
