No Power to dash, ignition or anything, battery is still good
 

Hi everyone,
Long time lurker, first time poster.

HereÂ’s the current situation. IÂ’ve had my 2017 BRZ since new, and crashed it in November 2022. Airbags and the seat restraints deployed and everything. I then decided to rebuild it and make it a project/track car. I found a full front clip with everything needed to get the front end in order. I got that installed, and everything was looking great. Car was starting, running and driving great However I decided to take a look at the engine bay fuse box because passenger side fan wasnÂ’t kicking on when at operating temperature. I took a power probe to the box and saw we had power going to the relay, and used the power probe to send power to the fans, and the fans kicked on. After that whole discovery, I decided to probe the whole box to see what else I can power on. Then, like an idiot :bonk:, sent power directly through drl relay and heard and saw a spark in the fuse box. I have no lights in the dashboard, no power to the ignition or the fuel pump. I checked all the fuses, nothing popped. Battery still showed 12.6 bolts on the tester. ItÂ’s as if the battery is dead. I think itÂ’s the pcm but IÂ’m not entirely sure what is wrong with this thing.

TLDR: I sent power through fuse box and now car is dead. Please help.

Check the fuse at the battery.

Checked that fuse and replaced with new spare one I had. No result.

OK was worth a shot.
Check the ground of the fuse block. Should be securely screwed down.
