How do you replace injectors on a Nissan 300zx?

To replace the fuel injectors on a Nissan 300ZX, first disconnect the negative battery terminal and relieve the fuel pressure by removing the fuel pump fuse and starting the engine until it stalls. Next, remove the intake manifold to access the injectors. Disconnect the electrical connectors and fuel lines from the injectors, then remove the old injectors from the fuel rail. Install the new injectors, ensuring seals are properly in place, reassemble the intake manifold, reconnect the fuel lines and electrical connectors, and finally restore fuel pressure and check for leaks.
