Hello all, new here.
Having an issue with the unit starting. When I turn to the accessories everything works. Fans, lights etc.. As soon as I try to turn to ignition to start it everything dies.
Battery is new.
Did notice that the ECUs lighy is not coming on it that helps. Any info where I can go from here would be helpful. Tried 2 ECUs.

Sounds like a bad ignition switch:
White/Blue: Acc or On
White: On only
Black/Red: On or Start
Black/White (and Black/Yellow if present): Start only

Okay, ill give that a test. Would that also effect the ECU from coming on. Not getting a 12V constant on my voltmeter from PIN 58.

Sure. If it's not getting an ignition signal then it won't power up.

Check your battery terminals as well. If they are corroded, it could have enough power to turn accessories on, but not enough to juice the starter.
