runs and dies

  1. 04.5-05 LLY Duramax Powertrain
    O.K. So I was installing my stereo, left the truck over night. Got in the next day fired it up and it dies right away (no smoke, no rough stop, just like I turned the key off) The Accessory position on the key does not work, windows don't work, locks don't work, interior light does not come on...
