2 Answers
f3's fuel pump relay is located on the wiring harness assembly. The fuel pump relay control circuit can adjust the fuel pump's power supply line via the relay based on changes in engine speed and load, thereby controlling the fuel pump's operating speed. The F3 is a BYD vehicle, with dimensions of 4533mm in length, 1705mm in width, and 1490mm in height, and a wheelbase of 2600mm. This car is equipped with a 1.5L L4 engine featuring natural aspiration, delivering a maximum horsepower of 109ps and a peak torque of 148nm. It is a 4-door, 5-seater sedan with a 5-speed manual transmission.
If you're looking for the BYD F3 fuel pump relay for the first time, don't panic. It's mostly located inside the fuse box in the engine compartment. Park your car, turn off the engine, engage the handbrake, open the hood, and look for the black plastic box on the right side—it's called the fuse relay box. Open the lid and check inside; you'll see several small black squares, which are the relays. The exact position can be identified by the label on the box cover, marked with 'Fuel Pump' or similar wording. If the label is worn off, refer to your car's user manual—it definitely has detailed diagrams. You can also try starting the car; if the fuel pump doesn't make a humming sound, the relay might be faulty and need replacement. If you're doing it yourself, wear gloves to prevent static electricity. It's advisable to regularly clean the box to prevent dust and rust, which can easily cause malfunctions. Take some time on a day off to familiarize yourself with its location so you won't be clueless when minor issues arise. If you encounter problems, don't push through—drive to a nearby repair shop for quick handling. Pay attention during regular use to reduce the chances of relay aging.
