However, the most common location is in the underhood fuse box (Power Distribution Center or PDC). This fuse box is typically located near the battery, often under a plastic cover.
To find it:
1. Locate the underhood fuse box: It's usually a large black plastic box.
2. Open the fuse box cover: You might need to remove a few screws or clips.
3. Consult the fuse box diagram: This diagram, usually found inside the cover or on the underside of the cover, shows the location of the relays and fuses. Look for a relay labeled "Fuel Pump" or a designation that clearly implies the fuel pump circuit (such as a label indicating the associated fuse). The diagram is crucial because the relay's position varies.
Important Note: If you don't find it in the underhood fuse box, some less common locations may include a secondary fuse box (though less likely on a 1994 model) or even mounted directly to the fuel pump module itself (though this is rare on this model). Refer to your owner's manual or a repair manual specific to your 1994 Buick LeSabre for definitive placement. A Haynes or Chilton manual will be helpful.
