If you are using a 1998-1999 PCM for a car with an automatic transmssion, it is possible that you may not have jumpers installed on the PCM. Ford disabled the jumpers on some vehicles meeting the above description. If your vehicle falls within this group, it is possible that it will not start with our chip. Some affected PCM’s are GTG1, BTB1, and MSE1 among others (although not all PCM’s with these catchcodes are affected).
