So i tested my ignition switch with the key turned on and no wires had power.

 

Fuses? How did you test it? Might need a ton more info about the car and what's going on.

 

i tested every fuse with the battery connected and with a fuse tester. they are all ok. i tested the ignition switch with the key turned to on and with the battery connected. ive bene having the same issue for about a few months and cant find out why.

 

There's a wiring diagram in this thread : https://www.rx8club.com/series-i-int...-manual-49075/.

Maybe that'll help trace it. Note there are 2 fuse boxes. What is the actual issue that caused you to start measuring stuff? Car is not starting? Is the immobilizer light on?

 

The original issue was that nothing inside the car has power, but everything in the engine bay does have power.

 

Sounds like the Room fuse. #15 in the driver's footwell fusebox afaik

 

hey, so I tested my room fuse and it is okay, but I tested all the wires going to the cabin fusebox and none of them have power. I'm completely lost and don't know what to do anymore.

 

Upstream from the Room is the BTN 30 amp fuse. Do you have power to that?

 

I tested the btn fuse and it has power

 

So it sounds like you have a break between BTN and the driver's footwell fusebox. Maybe sound the harness from BTN to the Room fuse?

 

How do i do that?

 

1. I'm having a problem with my wiring as well. I had to replace a few mainly the wiring from the battery on. But, now the car won't start. Can someone please help with diagrams of how the wiring is supposed to be ran?
