Behind the engine is odd. Could it have been coming off the starter and up along the firewall? Does anything electrical work?
Do me a favor. I need you to start by checking three of the maxi fuses in the underhood fuse box. Take a look at the pic below. In addition to checking the fuses, make sure power is present.
Let me know what you find.
See pic below.
