    help!!!!no power to no3 injector.

    Hi all,
    My car is running on only three cylinders at the moment. I have narrowed the cause down to it being no power coming from the ecu on pin 103, what should be live is just coming out as an earth. Anyone got any ideas as i am stumped!!!

    Thanks Dan

    If your ok with a soldering iron then I would open up the ecu and check for blown components or dry solder joints.

    The ecu grounds injectors - it doesn't supply +12v. All injectors should get +12v on one pin and the other pin goes to the ECU.

    My guess is that your dropping resistor back is faulty.
