    engine will not crank

    well building a 35 pick up kit but figured there are more people looking here , Heres the problem, not fully wired , still need to wire in the gauges , lights ,etc. how when I turn on ignition switch the engine will not crank and the solenoid makes no noise, I think there is no power going to the solenoid throught the blue wire ? any thought would be helpful
    Thanks Herb

    First things that come to mind is either the neutral safety switch, or clutch safety switch are not in place or not bypassed.

    Is the clutch safety switch wired correctly?

    Use a test light and make sure you have power coming out of the switch....could be a bad switch.

Without a safety switch or if the two sides of the wire are not joined together the start circuit is open.

    Herb if you do not have a clutch safety switch you must join the 2 blue wires together that are near the pedal area. Since you have an Automatic you may have tied it to the Park or neutral switch for the trans.
