2001 Merc Cougar Electrical Problems, Won't Start
Yesterday, for the first time I used my spare key to drive my cougar, parked it over night and all was well. Today, when I went to start it, the car unlocked fine, and the dash was working. I put the key in and turned it, everything went dead, the dash, lights, the ding.
We tested the battery, its fine. The solenoid of the starter, when the key is turned, is not recieving any power. We've tested some of the relays and fuses for the starter, the junction box itself is recieving power.
With the key turned to accessory, the following happens:
what works in the car:
What doesn't work:
When the key is turned to ignition(start), everything dies.
It seems as though anything internal, possibly anything not run through the computer, seems to be working until the key is turned over. It's obviously something electrical, but I don't know where to start. A possible short in a wire? Or perhaps the car's ECU died? Any help would be appreciated.
Also, when I was removing the air intake, I jiggled the air flow wire and my wipers turned on once.
