    It was just a starter bin for you, worked fine in car I used it on, I hope I gave you the right one? is there an error code set? Did the motor run on another bin?

    DTC codes? Are there any error codes set? Is your check engine light hooked up? Turn key on but don't start engine. Does CEL come on, blink and stay on with key on? Go off when engine is started?

    Yes. Called MIL (Malfunction Indicator Light/Lamp) in this wiring diagram.

    There was never an Iron Head Manual trans. But here are the bins we have.

    Did that one not work? You never said what the CEL was doing or codes?

    Have you tried to connect to data with TunerPro? Record some data and post here so we can see what it is doing.

    Do you have wirless internet near car? Do you know how to allow remote access? May be quicker to set up data/ADX file if I did it?

    If it runs and dies on all bins then stick to the one I gave you. It is the only steel head manual trans bin in existence.

    What is your batterey voltage when idling? What is fuel pressure? CEL? This is a transplant and many things can go wrong.

    fuel pressure is about 40-41 psi at idle. 13.8 volts at idle. im running ur 95COP bin it runs on it but it wants to die but then it revs up,goes normal idle then does it again. Could oxygen sensors cause it? and no i dont know how todata log, im using the uber-easy aldl cable.
