Guest Blue02wrx Posted February 12, 2004 Share Posted February 12, 2004 ok with the key out of the ignition i have power on both sides of the injector clip. if i unplug all injectors, each one has power on one side but pulses on the other side like it is firing. if i plug one in they go back to both solid hot. i think it is a ground issue but i have tried every ground location and no luck. does anyone have any suggestions or know what the heck is going on???!!!! i need my car back.

SleeperZ Posted February 13, 2004 Share Posted February 13, 2004 The way the injectors are controlled by the ECU is by running +12V (battery) to one side, common to all injectors. The injector is energized by running the other connection to a "ground" (chassis). Current will not flow unless the ECU pulls the side not connected to +12 to ground. It sounds to me like your problem is elsewhere, and not in the injector wiring. I hope you are asking about a Z injection system Quote Link to comment Share on other sites More sharing options...
Guest Blue02wrx Posted February 13, 2004 Share Posted February 13, 2004 have you gotten any suggestions on why it floods out so bad....i replaced the head temp sensor and put a different afm in it...are there any other things that would cause the injectors to be wide open??? could a sensor be bad, a ground not right,m or some wires crossed.

SleeperZ Posted February 13, 2004 Share Posted February 13, 2004 Without knowing more details about the issue, all I can say is to check for stuck injectors or an ignition problem. Bad plug wires or other problems on the high voltage side of the ignition will cause flooding in addition to bad injector drivers inside the ECU or stuck injectors. You might check fuel pressure too, as a bad pressure regulator will cause a very rich mixture. Quote Link to comment Share on other sites More sharing options...
DatsunBoy77 Posted February 13, 2004 Share Posted February 13, 2004 Once i must of hit my coolant temp sensor and knocked the plug off. It would just start and flood and kill the plugs. Is yours flooding trying to start or after? Quote Link to comment Share on other sites More sharing options...
