2004 escalade will not start
Battery is ok but gauges don't move when key is turned no check
lights on no security issues on screen
Check for blown main fuses in the power distribution box, if those check good, hookup your preset saver unit and then check your battery terminals and clean if needed. On a lot of these late model vehicles if they loose battery voltage the BCM will lock out everything then you have to be towed to a dealer and the system reset. Hope it is just a main fuse.
