    90 crx hf Has no spark after I replaced Head Gasket?
    It has Voltage at wires going into distributor when ignition is on, but no farther in. I put a test light on fuel injector and while engine was being cranked light was pulsing.. So I thought Igniter Control Module was bad so I replaced that and I have same issue. I can hear main fuse relay click when ignition is turned on, also can hear fuel pump working properly. I checked ECU and Its throwing code 15 "IGNITION OUTPUT SIGNAL" Which also led me to believe it was Igniter But It's not. All wiring looks good, and like I said test light Lights up when touched on wires Going into Distributor when ignition is on. Please HELP! IM IN A TIME CRUNCH=(

    So the test light at the injector harness flashes during cranking, that means you're getting cranking RPM to the ECU and the ECU can pulse injectors, but it's setting Code 15. My guess is you're not getting any spark, correct?
    The flow chart for that DTC shows the fault to be either the Igniter or the ECU.
    Does the Tachometer move at all when you are cranking the engine?

    Yes there is no spark, TACH does not move at all when cranking, ECU should be good because LED lights up when car is Ignition is turned on. Right? And I replaced IGNITER With brand new one yesterday. Didn't help. Is it the Ignition Coil? Thanks for the answers!

    I got it fixed there were wires coming from the fuel injectors that were wrapped in tape and had wire connectors on them, Unwrapped the tape and one of the wires were pulled out of a connector. Rewired it and Fired right up. Thanks though! Maybe somebody is having same issue
