1. Open the hood of your Corolla.
2. Locate the driver's side strut tower. It is the black metal tower located near the front of the engine compartment.
3. Look for the fuel relay. It is a small, black box with two electrical connectors on one end.
4. The fuel relay is usually mounted on a bracket near the strut tower.
Once you have found the fuel relay, you can remove it by disconnecting the electrical connectors and then removing the mounting bolts.
