    I have a 1990 300ZX Z32 TT Auto
    The problem is I have no power at the EFI plugs? The Zd has a brand new engine harness,AMF,TPU and TPS.
    All plugs are connected and I have done a code test with nothing on the laptop. I have spark and the car will run on airo start,any ideas?? Im thinking its the ECU? Timing was also done a few weeks ago and all good.
    Thanks

    Obviously the place to start is to check for continuity between the injector connection plugs & the ECU.

    Hi Terry.
    I had a very similar problem not too long ago. I installed a brand new wiring specialties harness and forgot to plug in one connector from the main harness to the efi harness just before the connector to the ecu.

    It could also be the green fusible link for fuel pump and eng inj.
    Before that fuse, power is fed directly from the postive battery lead but if your getting voltage to coils then i'd say prehaps the ground connection is faulty.
    I would check the voltage at the fuse
