1. Consult your Firebird's owner's manual: This is the best place to start. The manual will have a diagram showing the location of all relays and fuses.
2. Check under the hood in the fuse box: Many Firebirds have the fuel pump relay located in the under-hood fuse box. This box is usually near the battery. The relay itself may be labeled, or you might need to use the owner's manual to identify it.
3. Check the passenger compartment fuse box (if applicable): Some models may have the fuel pump relay inside the car, typically under the dashboard.
4. Look for online forums and resources specific to your year and model: Search for "[Your Firebird Year] Firebird fuel pump relay location" on forums like Pontiac enthusiast websites. This will likely yield the most accurate information.
Without knowing the specific year of your Firebird, providing a precise location is impossible. Always consult your owner's manual first.
