More specifically, you should look on the driver’s side of your vehicle next to the battery. There, you should see your car’s Intelligent Power Distribution Module, which will have your fuel pump relay (among other fuses and relays) inside.
If you have trouble finding the proper relay, you may want to consult your owner’s manual for more details. If you don’t have a copy of your manual, don’t worry! You can find owner’s manuals for most vehicles online.
