    Try this, disconnect the harness wire from the pos. + side of the coil.

    Connect your jumper from the battery pos. + side to the coil pos. +side and crank it over.

    If it runs good, then you know there is a problem in the power supply from the ignition switch and in the harness.

    Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.

    Education is expensive. Keep that in mind, and you'll never be terribly upset when a project goes awry.
