    After tune security lock out?

    Can anyone help me, just updated a new E-tune, and the security locked the starting out. I turn key on everything works...no crank, I hear the relay clicling in there.
    The tune isn't anything crazy.

    Its a 2008 suburban e38

    All came down to a bad ground. Which disabled the airbags and the 4x4 engagement and caused a no crank.
