To change the fuel pump on a 1979 Datsun 280ZX, first, disconnect the negative battery terminal and relieve fuel system pressure by removing the fuel cap and disconnecting the fuel pump relay. Next, locate the fuel pump, which is typically mounted on the frame rail or near the fuel tank, and remove the necessary screws or bolts.

The 1975 Datsun 280Z does not have a fuel injection relay as it originally uses a mechanical fuel pump and a carbureted system. However, if the vehicle has been modified to include a fuel injection system, the relay would typically be located in the engine compartment or near the fuse box. It's best to consult the specific wiring diagram for your modified setup or refer to the manual for guidance.
Why does the fuel gauge run's backward 79 280zx?
In a 1979 Datsun 280ZX, the fuel gauge running backward is often due to a malfunctioning sending unit in the fuel tank or issues with the gauge itself. The sending unit may be improperly calibrated, or there could be a wiring issue causing incorrect signals to be sent to the gauge. Additionally, a short circuit or faulty ground connection can also lead to erratic gauge behavior. Diagnosing the problem typically involves checking the wiring and testing the sending unit for proper function.
How come your 1983 Datsun 280zx wont idle?
If your 1983 Datsun 280ZX won't idle, it could be due to several reasons, such as a vacuum leak, which disrupts the air-fuel mixture, or issues with the idle air control valve. Additionally, a dirty or failing fuel injector, a clogged fuel filter, or problems with the ignition system could also prevent proper idling. Checking the fuel delivery system and ensuring all connections are secure may help diagnose the issue. Lastly, a malfunctioning throttle position sensor can also affect the idle speed.
Can you reprogram the ecu on a 280zx?

The process typically involves using a tuning software compatible with the vehicle's ECU to modify fuel maps, ignition timing, and other parameters. However, keep in mind that the 280ZX's ECU is relatively basic compared to modern vehicles, so options for extensive reprogramming may be limited. It’s advisable to consult with a professional or an experienced tuner familiar with classic Datsun vehicles.
