Witk the fuel rail off, and key on it would not stop spraying fuel out of injector #4. I switched the injector and with the key on and the fuel rail out. It keeps spraying fuel out of # 4 injector again. Since it's not the injector on #4. What else could it be?

    Got to be ECM or driver circuit to # 4! Pro. scanner is a must for diag. Think of the injector as a bulb it has to have power and ground to work. Before it can flash something has to break one of these circuits. May be a short to either + or -!
    Or a defective computer. Check circuit with DVOM. Then compare with another injector connector. I think it is an ecm problem.
    But you have the car so, good luck.

    I have continuous power to one injector. I want to check for a grounded wire. Does anyone have a wire diagram. I have a Hynes manual but it doesn't come with a diagram. Can I bypass the wiring harness, by going from ecm to the injector. Then check for continous power?
