* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery. Look for a relay panel within the fuse box; the fuel pump relay might be labeled or you might need to refer to a diagram.
* Under the dash: Less common but possible, especially on some models. This would be within a fuse panel or relay panel under the dashboard.
To find it definitively:
1. Consult your owner's manual: This is the best first step. The manual will have a diagram of the fuse and relay boxes.
2. Use a wiring diagram: A wiring diagram specific to your 1989 Chevy Celebrity (you'll need the VIN for precision) will show the relay's location and circuit path. Online auto parts stores often have free diagrams (though registration might be required).
3. Look for markings on relays: Once you locate the fuse/relay boxes, examine the relays themselves. Some might have markings indicating their function (though not always).
4. Use a multimeter: If you're comfortable with basic electrical testing, you can use a multimeter to trace the fuel pump circuit and find the relay that controls it. However, this method requires some electrical knowledge.
Remember to disconnect the negative battery cable before doing any work with electrical components to prevent accidental shorts or damage.
