96 4.0 auto. Ran fine one day. Went out to start it and nothing. No key on power. No dash lights, no radio, no fuel pump. Headlights work bright, dome light works, brake lights work. I'm stumped, not much of an electrical guy. One day a few days before I was sitting in it after just driving it, ignition off and heard some strange sounds under the dash, steering column area, but it ran fine and everything worked. Wondering if its related and something was burning up but I can't find anything.

 

So....everything that runs through the ignition switch is dead, things that are directly powered still work. Pull the ignition switch and have a look. Check the connector too, both are common failures and I think yours just did.

 

Like Radi! That would be you best place to start looking.
