How do I make the new ECM learn the car. I got an ECM from autozone and supposedly they programmed it to my car. I gave them the VIN and the mileage. But I get no response when I try to start the car.
If you put in a new ECM and nothing has changed.... it wasn't the ECM in the first place. Look at the ignition coils, the cam position sensor and the ignition switch

Find the Ecm under the hood on the passenger side and unbolt it from the firewall or fender wall and then take out the 10 mm bolt holding the wire plug in and just reverse putting it back together.. OH.. First remove the battery cable and you might want to check that your "New" Ecm is set up for your Ram 50.. Most ecm's have to be pre-programmed for make year model and Vin number..
Flash programming required ON or OFF the vehicle.Accurate VIN and mileage are required. Additional vehicle specific on-car programming must be performed AFTER installation to prevent drivability and starting issues.
The following service procedures require either a programming or a setup event performed for a complete repair.
ECM Replacement
Important: It is not necessary to program a new engine control module (ECM). The ECM is programmed from the factory. Ensure the new ECM is equipped with the latest software/calibration.
If the engine control module (ECM) is replaced, the following procedures must be performed:
Idle Learn Procedure--Refer to the appropriate procedure:
• Idle Learn for the 1.4L DOHC engine
• Idle Learn for the 1.4L SOHC engine
• Idle Learn for the 1.6L engine
The crankshaft position (CKP) System Variation Learn Procedure-- Refer to the appropriate procedure:
• Crankshaft Position System Variation Learn for the 1.4L DOHC engine
• Crankshaft Position System Variation Learn for the 1.4L SOHC engine
• Crankshaft Position System Variation Learn for the 1.5L engine
• Crankshaft Position System Variation Learn for the 1.6L engine
Theft Deterrent--Refer to Programming Theft Deterrent System Components . The ECM will learn the incoming fuel continue password immediately upon receipt of a password message. Once a password message is received, and a password is learned, a learn procedure must be performed to change this password again. An ECM which has been previously installed in another vehicle will have learned the other vehicle's fuel continue password, and will require a learn procedure after programming to learn the current vehicle's password.
The ECM must be programmed according to the VIN. I suppose you did this already. In addition, I understand that the ignition transponder key must also be computer matched to the ECM. If not the car eill not even turn over. Good luck
The ECM (Engine Control Module) has to be programmed based on vehicle identification number to teh vehicle it is installed in. Purchasing a computer box via a remarketer or parts store gets you a blank computer that has to be "flashed". If this was a self install job you can take the computer to the dealer and have it flashed, be sure and get the VIN off of your car. Typical cost for a computer programming on vehicle is (based on geography) 100-300 dollars. Since FIAT is a foreign model it might be in the higher end of that range. Even with the ECM flashed you may either not start or if it does it will run rough for the first drive cycle while the vehicle ECM learns the parameters of your car and adjusts accordingly.
Charlie. You have replaced the ECM on your van?.
Kedwin,, Your problem is, the computer on that 3.3 L.
Need to be programed with the VIN nember of your car.
The Antitheft System will disable the injectors due a incorrect VIN, Bucause the body computer is not recieve the correct pasword between 5 seconds after start up.
YOU have 2 options. 1 get a ALOHA Smith. some of they have the computer required to program ECMs.
The other option is: Get a new ECM from the dealer, They will program if ask for that.
NOTE:::::: Other way is . Put the body control module with the computer from the same car.
OK... I hope this work for yours.
If NOT letme know I can look for more information.
Thank you.
