* Under the hood in the fuse box: This is the most common location. The fuse box is usually located either near the battery or on the driver's side fender well. Look for a diagram on the inside of the fuse box cover to identify the fuel pump relay. It might be labeled "FP," "Fuel Pump," or have a symbol representing a fuel pump.
* Under the dash: Less common, but possible, especially on some models. You'd need to inspect the fuse boxes or relay panels under the dashboard, possibly behind the kick panel on the driver's side.
To be certain:
1. Consult your owner's manual: This is the best resource. It will have a diagram of your fuse box and relay locations.
2. Use a wiring diagram: A wiring diagram specific to your 1992 Pontiac Bonneville's VIN will pinpoint the relay's exact location. You can often find these online through automotive parts websites or repair manuals.
3. Check online forums: Search online forums dedicated to Pontiac Bonnevilles. Other owners may have posted photos or details about the location of their fuel pump relay.
Remember to disconnect the negative battery terminal before working with any electrical components to avoid short circuits.
