Definitely grab a known working battery from another car.
If you've blown the edu fuse, could the dash fuses be gone too?
Could be a Dodgey key barrell going to ignition.
Try powering the starter directly with some jumper cables. Be careful though, it's easy to ground the positive down there.
Make sure you check fuses with a multimeter not just by sight. Also check if you have power to the battery side of the fuse.
Check ecu is getting power on ignition also.
