To find it, you'll need to do the following:
1. Consult your owner's manual: This is the best place to start. The manual will show you diagrams of the fuse and relay panels, and should clearly identify the fuel pump relay.
2. Check the underhood fuse box: This box is usually located near the battery. Look for a diagram on the inside of the fuse box cover. It might list the relay as "Fuel Pump," "EFI," or something similar.
3. Check the interior fuse panel: This is typically located under the dash, often near the steering column or center console. Again, look for a diagram showing the relay locations.
4. Look for a separate relay center: Some vehicles have a separate relay center, often located near the fuse boxes. This is less common but possible.
5. Use a wiring diagram: If you can't find it visually, you'll need a wiring diagram specific to your 1992 Oldsmobile Toronado. These can sometimes be found online through repair manuals or forums dedicated to Oldsmobiles.
Important Note: Before working with electrical components, always disconnect the negative terminal of your battery to prevent accidental shorts.
