In many vehicles, yes, there is a fuse protecting the fuel pump circuit. However, sometimes the fuel pump is protected by a relay (which *may* have a fuse protecting the relay's power supply), or in some cases, there might be an inline fuse within the fuel pump wiring harness itself.
To find out if your car has a fuel pump fuse, and where it is:
1. Consult your owner's manual: This is the best place to start. The manual will have a fuse box diagram showing the location of all fuses and what they control.
2. Check the fuse box diagrams online: Many websites provide free access to vehicle repair manuals and fuse box diagrams. You'll need to know the make, model, and year of your vehicle.
3. Look in the fuse boxes: Your vehicle likely has one or more fuse boxes. Common locations are under the hood and under the dashboard. Examine each fuse box carefully. Some fuses may be clearly labelled "Fuel Pump," "EFI," (electronic fuel injection) or something similar.
4. Check for an inline fuse: This is less common, but some vehicles may have an inline fuse within the wiring harness leading to the fuel pump. This will require a visual inspection of the wiring near the fuel pump itself. This is generally not recommended unless you are familiar with automotive electrical systems.
Important Note: Working with car electrical systems can be dangerous. If you are not comfortable working with electricity or unfamiliar with your vehicle's system, it's best to take your car to a qualified mechanic. Incorrectly handling fuses or other electrical components can cause damage or injury.
