  • spark, fuel, but no injector pulse

    all my fuses under the hood are good. the fuel pump comes on, the spark is good, ,but i am not getting an injector pulse from the injector harness plug. i'm just about stumped as to what could be causing this.

    SOMEBODY HELP ME PLEASE!!!!!!

    Ignition module missing a plug? Or bad perhaps?
