Ok guys going to try this one more time. I have a 98 limited. I have replaced the battery, ignition switch, and all the fuses. When I put the key in the ignition it beeps. When I turn the key there is a relay that clicks and that is it. I just replaced the heater core a couple weeks ago. There are no dash lights, no movement on anything on the dash. I don't hear the fuel pump. Plz help I am lost and I don't wanna have to get rid of my jeep.

 

Check your battery cables, particularly the terminals at the battery. I had similar symptoms and when I went to remove the battery the connector was broken in half.

It provided enough juice to power the courtesy systems (lights, locks, etc) but not the critical ones.
