injector connector
How can I test my injector connector to see if it's damaged inside? I have power at the ground wire (all the time) with out the key on. Injector always stays on, I have checked this with fuel rail off. I traced the driver wire to PCM, wire is not damage. Is there a free way to test the PCM to the pin, to see if there is always power? Could my injector cause the PCM to go bad, mine is always running. Maybe it overheated or something?

What????
Okay, first off what kind of vehicle are we working on? And I mean the year, make, model and the engine it's equipped with. Second of all, most modern fuel injected gas engines (at the least the ones I'm familiar with) control fuel injector pulse through the ground side of the circuit (so there should be B+ to the one side of every injector connector at key-on/engine-off and key-on/engine-running). If I understood correctly, you are attempting to verify circuitry, correct? Why not just take a "peanut bulb" (any standard 194 bulb used for license plate lights for most vehicles) and insert it into the fuel injector cavity one at a time to see how it "behaves". This test should give you a very good visual interpretation if the PCM is commanding the injector in question wide open.
