My son lost the key to our 2002 Mercedes Benz ML320. Instead of replacing the key, my ex husband ripped out the ignition thinking he would bypass the programming issue. Of course that didn’t work and now he has replaced the steering column with ignition and key and ecm from salvage but the car still won’t run unless he pours gas into the breather. Could someone tell me the problem and what he needs to do now, please? Thanks in advance.
