Is there a ecm that will fit a 2004 Crown Vic that does not have the PATS system on it ?
And if so, will it run the car "right" ?
I read in a Haynes manual that Police cars don't have the PATS system in there ecm
if the theft light is flashing that means the key is not programmed or there's a problem with the transciever or wiring if you have multiple keys try another key and if theft light still flashing most likly keys need to be programmed and you will need two pats keys to program
