* Under the hood, in the fuse box: This is the most common location. The fuse box is usually located near the battery. The relay itself might be labeled, or you may need to consult your owner's manual or a wiring diagram to identify it.
* Inside the passenger compartment, under the dashboard: This is less common but possible. Again, you'll need your owner's manual or a wiring diagram to pinpoint it.
To find it:
1. Consult your owner's manual: This is the best first step. It should have a diagram showing the location of all relays and fuses.
2. Locate the under-hood fuse box: Open the hood and look for a plastic box containing fuses and relays.
3. Look for a relay labeled "Fuel Pump" or a similar designation. Some relays might not be explicitly labeled.
4. If you can't find it in the under-hood fuse box, check under the dashboard. This will likely require more searching and potentially some panel removal.
If you're still having trouble, searching online for "1994 Geo Tracker/Suzuki Sidekick fuel pump relay location" along with your engine size (1.6L or 1.8L) may yield helpful images or forum posts from other owners who've tackled this. Remember to disconnect the negative battery terminal before working with electrical components.
