If you have a car, then you have a fuse. Fuses are devices that contain and control the flow of electricity in your car. They are designed to protect your car's electrical system from overloads and damage.
The stud 1 fuse is located in the engine compartment of your car. It is usually located near the battery. This fuse protects the electronic control module (ECM) and the fuel injectors from overloading. If this fuse blows, then your car will not start.
