2002 Kia Spectra All electrical went dead after 1-2 seconds

I went in to start the car this morning, put the key in the ignition, and everything came on as normal for about 1-2 seconds then went completely black. No power to anything in the car - nothing.

Would a bad engine control module do something like this out of the blue? Or does it sound more like a relay or fuse? I would like to try to troubleshoot before I pay big bucks to a repair guy on an old car to fix.

I would appreciate any recommendations you may have.

Thank You,
