A fuel injection fuse is a safety device that protects the fuel injection system in a vehicle from electrical damage. It is a small, cylindrical device with a metal contact on each end. When the current flowing through the fuse exceeds a certain level, the fuse will blow, breaking the circuit and preventing any further current from flowing. This can protect the fuel injection system from damage that could be caused by an electrical overload or short circuit.
Fuel injection fuses are typically located in the fuse box, which is usually under the hood of the vehicle. They are usually labeled with the circuit they protect, such as "Fuel Injection" or "EFI". If you experience problems with your vehicle's fuel injection system, it is a good idea to check the fuel injection fuse to see if it has blown. If the fuse has blown, it will need to be replaced before the fuel injection system can be repaired.
