Ok, I was wondering if anyone would like to try to wrap their brains around this issue I'm having.
The car is a 2003 Subaru WRX.
Problem: Yesterday, I met some friends for lunch. Up until that point the car was working perfectly, not even a hint of any sort of electrical issue. No stuttering or oddball behavior. When I went back to my car after lunch, I couldn't start it.
Here's the oddness. The key does nothing. The car has power, and whatever detects the key in the ignition starts dinging. However there is no response to turning the key. No accessories power up, nothing ignition related (fuel pump, windows, status lights on dash, etc.) powers up either. The car behaves exactly as if all I did was slide the key into the slot and never turned it.
What I've done:
Checked fuses. Any fuses ignition related check out. Plus this doesn't explain the lack of accessories. Other items that don't require the key work fine (parking lights, interior lights, etc.)
Pulled the igntion switch. I was getting some odd results with my multimeter when I checked the ignition switch. So I pulled it and double checked. The results were inconsistent. Sometimes the switch would connect the proper leads, other times it wouldn't. And some times I'd see cross-talk between the IGN and ACC curcuit. So, thinking that was my problem, I cut the switch from its harness and tried to "hotwire" the car directly. No good, same exact behaviour; No Accessories, no ignition, no starter.
So I'm at my wits end. If I can't get this at least diagnosed by Monday, I'm going to have to take it to a shop. And considering it's electrical, I'll probably have to take it to a dealership.
So any ideas would be a great help.
