Taking a shot someone might be able to help me with this. It's been to the shop 3 times and they are stumped.
I have an '89 RS with a 302 automatic.
I live in MN and when the weather gets below about 10 degrees the car will not do anything when I turn the key. Radio and heater will work with key in on position but the ignition and starter will not activate at all. The symptoms are exactly the same as when the factory security kicks in and shuts the ignition down for about 5 minutes. Once the outside temp starts rising it will start normally.
Thanks for any leads you can give me. All the the wired conections have been cleaned and checked..
