I have a 2006 Sebring conv. that got hit in the left side nose and smashed the ECM. I replaced it but now the engine will not turn over. If I jump the starter relay it will crank but not start. Can anyone offer suggestions to what might be the problem? Thanks in advance.

 

The PCM needs to be programmed for that vehicle by VIN number. You can't just take a PCM either off the shelf or out of another car and expect it to work.
Also, if the car got hit hard enough to wreck the PCM it probably damaged the battery and wiring in that corner. That's pretty had to diagnose via long distance. You might want to get some professional help up close and personal.
