I have a 2003 Pontiac Sunfire.
If I turn the key to 'ON', the electrics turn on. Lights, radio, fans, the works. Everything is normal. If I turn the key to 'START', then the whole car dies. Everything goes out, lights, fans, dash lights, everything. Turning it off then back to 'ON', and I get nothing.
If I leave it for a few hours, I can turn it back to ON and get the electronics will turn on. I've checked the fuses and they're fine.
Any ideas what could be wrong?
