Check at first the ignition 1 fuse in the rear fuse block. Check if it is open, but also check and see if there is power at that fuse. If there is no power at that fuse, it could be a faulty ignition switch. You can also try this first, disconnect the battery cables and short them together for a minute or so. Frequently, on the newer cars with multiple modules, they can experience a condition known to me as logic lock. Shorting the battery cables discharges the capacitors responsible for keep alive, and many conditions have been corrected with this simple procedure, it is worth a try.

Here is a guide that can help.

So when you say short them together, do you mean touch them? Also ign-1 fuse is out and showing nothing with tester

What do you mean 'tester'? Is it a volt meter, and there is no power to either side of ign 1 fuse cavity terminal with the key on? And that is correct, disconnect and touch both cables together for a minute or so. If there is no power at ignition 1 cavity, then there may be other problems. Reply with more details to this post.

This is great I bought a 2000 sts same exact problem as CHILL 1 had to jump my car once then all the same problems started I was kind of hesitant on touching the cables together but people were saying it could be an expensive fix even the mechanics weren't sure how to fix it withoit ripping things apart but I tried it and it worked perfect thank you guys saved me some $$$
