To find the correct fuse and relay, you'll need to consult your owner's manual. It will show you the fuse box diagrams that identify the specific fuse and relay related to the fuel pump (often labeled as "Fuel Pump" or something similar). The fuse is likely a higher amperage fuse than most others in the box. The relay might be located in the underhood fuse box or a separate relay center.
Without your owner's manual, I cannot provide the exact location. Looking at online diagrams is risky as they vary by trim level and options. Using the wrong information could damage your vehicle's electrical system. The owner's manual is your best and safest resource.
