1. Consult your owner's manual: This is the best place to start. The manual will show you the fuse box diagrams and identify which fuse(s) or circuit breaker(s) are related to the fuel system.
2. Check the under-hood fuse box: This is the most common location for a fuel pump related fuse.
3. Check the interior fuse box (if equipped): Some vehicles have additional fuse boxes inside the cabin.
4. Look for a fuse labeled: You might find a fuse labeled "Fuel Pump", "Fuel Injection", or something similar. It's also possible the fuel pump circuit is protected by a relay, which is often controlled by a fuse.
5. If unsure, use a multimeter: If you can't find it in the diagrams or by labels, a multimeter can help. With the ignition in the "ON" position, but not running, test the power at the fuel pump connector. If you don't get power, trace the circuit back to the fuse box using the wiring diagram. This should be done by a qualified technician unless you have electrical experience.
Important Safety Note: When working with fuses and electrical components, always disconnect the negative battery terminal first to prevent short circuits and injury.
