To search for a PCM/EMC/ECU for all makes & models of vehicles (Dodge, Toyota, Jeep, Pontiac, Chrysler) etc click here.

The PCM units from seller "fs1inc" will arrive Programmed & Updated to your vehicle's VIN (Vehicle Identification Number) with the most recent manufacturer updates. These updates will also help improve the performance and fuel economy of your vehicle. If your vehicle is PATS (Passive Antitheft System) equipped or has a computer chip in your key, you may need to have the keys reprogrammed by a Locksmith or Ford Dealer. If you do not have PATS, your Powertrain Control Module will be Plug and Play.

After you purchase below, send them your VIN number which assures you get the correct part as well.

If someone could provide a replacement video or more details/photos when replacing and send them to me, that would be amazing!
 
Looking for replacement PCM ford part no. 4w4z12a650zarm. My old unit is unrepairable. No longer available at ford distributors.
 
Do I have to unbolt part of the PCM from inside the engine compartment to remove it OR if I remove the glove box and fan box will I be able to get the PCM out from inside the car?
 
PCM REMOVAL:
  • Disconnect the battery ground cable.
  • Remove the cabin air filter plenum.
  • Remove the glove compartment.
  • Remove the components in the order indicated in the illustration and table.

2003 TBird wouldn't start. Mechanic tested and said could not establish communication with PCM/EMC/ECU. Rechecked grounds, reference wires, etc. again. Still unable to establish communication. Took PCM from 2002 TBird and had communications (knowing would not work in 2003 but just wanted to confirm could get communications.) Ordered 2003 PCM from Flagship One, installed, and still no communication. Flagship One says return and they'll double check to make sure have communication. Put in mail today. Am wondering what else might cause failure to communicate other than a bad PCM. Thanks for any help.
