ok.. so we put the key in to start the cougar.. the key turns over but doesnt start the car like it normally would, we noticed the security light flashing like crazy so im assuming it has something to do with either the key itself or the security having an immobiliser(didnt know if we had one so we wouldnt know anything about it) and it pretty much not letting us start it asthough its thinking where trying to steal it.. all other electrics work..
Would and electric diagram help?
Had an auto electrician look at it and all they could come up with was that under the main body earth had corroded under the fuse box???
Obviously this was wrong.. as a few hours after picking ip up from them.. we couldnt start it again.
In desperate need of help, not many mechanics know what they are doing as the town we live in has only one cougar.. ours!
