Ok, so i drove to a mates and stayed for about 10 minutes, get back to the car and it wont start. I've got no idea what it is and what it can be. So far Ive tried:

- Push start
- Disconnecting the Battery
- Checked Ignition fuse

What seems to occur is when i try to turn the ignition over there is a buzzing sound from behind the fuse box. Also all interior lights and stereo flash when I turn the key

Any Suggestions??
