PCM problems
 

I have a '98 Chrysler Concorde thats been running fine, until one day it wouldnt start. NO lights or warning
I took it to a dealership that said the Powertrain control Module needed to be replaced.... they replaced it and it still wont start. They said they dont know why it wont synch to the car... has anyone heard of this or know what it could be???:confused:
