* Under the hood in the fuse box: This is the most likely location. Check the fuse box (often located near the battery) carefully. The relay itself might be labeled or you might need to consult the owner's manual or a wiring diagram to identify it. Some fuse boxes had a separate relay section.
* Under the dashboard: Less common, but possible. This is usually near the fuse panel under the dash.
* In the trunk: Highly unlikely for the fuel pump relay on this model, but possible in some GM vehicles.
To find it, you'll likely need to:
1. Consult your owner's manual: This is the first and best place to look. It might have a diagram showing the location of relays.
2. Use a wiring diagram: A wiring diagram specific to your 1989 Chevrolet Celebrity Eurosport will show the location and circuit of the fuel pump relay. You can find these online (often on sites specializing in automotive repair information, some are subscription-based) or at an auto parts store.
3. Look for a relay that is larger than the others: Fuel pump relays are often physically larger than other relays in the fuse box.
4. Visually inspect the relays: If you can't find a diagram, carefully examine the relays in the fuse boxes and compare them to pictures online labeled as "fuel pump relay" for a similar year and model.
Important Note: Working with automotive electrical systems can be dangerous. If you are not comfortable working with electricity, it's best to take your vehicle to a qualified mechanic.
