Hello and thank you for trusting Just Answer with your question. I'm Dj and I will work with you on this.
The first test is to use a test light and check all the fuses in the fuse box with the key on.
This will determine if the fuses are getting power. I expect that one of the larger fuses that power all of the smaller circuits blew. If this is the case, several fuses won't have power on either metal lug on the fuse.
Please let me know what you find.
