How do you test the starter relay on a 1991 Toyota pickup?

To test the starter relay on a 1991 Toyota pickup, first, locate the relay in the fuse box. Use a multimeter to check for continuity by connecting the leads to the relay terminals while activating the ignition switch; you should hear a click if the relay is functioning properly. Additionally, you can bypass the relay by connecting the terminals directly to see if the starter engages, indicating a faulty relay if it does. If there's no continuity or the starter doesn't engage, the relay may need to be replaced.
