why does my durango die when i replaced ecm
replaced ecm in 04 durango. the new ecm from identical durango. car starts and runs pefect for 10 seconds and dies. it will do this as many times as i want to try it. whats up do i have to do something to the ecm or what. please help me.
sounds to me like the ecm you put in it has security enabled on it and needs to have the keys programmed into it. Try and start the car and check to see if the security light comes on and stays on. if the security module is not happy it will stop the engine after a couple of seconds. hope this helps
one other thing is you might have to get the pinion factor reprogrammed in your abs because you switched the ecm. I know on 2003 and under as soon as you plug in a new ecu it wipes the abs programming and continues to ding nonstop when the engine is running.
