Why is fuel pump relay on a 1986 Nissan 300zx non turbo not working?

The fuel pump relay on a 1986 Nissan 300ZX non-turbo may not be working due to several potential issues, such as a blown fuse, a faulty relay itself, or wiring problems like corrosion or shorts in the electrical connections. Additionally, problems with the ignition switch or the fuel pump can prevent the relay from activating properly. Testing the relay and associated components with a multimeter can help identify the specific cause. If necessary, replacing the relay or repairing any damaged wiring can restore functionality.
