yakimaz Posted February 10, 2011 Share Posted February 10, 2011 What is it that times the injectors initially? I just rebuilt my engine, installed it correctly(I think) and the injectors are not firing. It ran when I pulled the motor, but needed a full rebuild. I have a full wiring diagram, but can't find where the injectors are timed from. Any help would be appreciated. Quote Link to comment Share on other sites More sharing options...

NewZed Posted February 10, 2011 Share Posted February 10, 2011 (edited) It is fairly well described in the Engine Fuel section of the FSM. The ECU grounds the injectors, allowing current to flow and opening the injectors, off of a pulse from the negative post of the coil,when the coil fires. This circuit also runs through the tachometer, so if the tach is disconnected the injectors won't fire. The injector connectors should have 12 volts on both wires, when the key is on. The 1976 280Z FSM chapter files at www.xenons30.com are well-copied and broken up in to individual chapters, so very easy to find what you need.
