Hello, the car was running and the gas line came unplugged and didn't see it, so
I diagnosed it wrong and upset the ECM. I've been trying to replace it with a
refurbished one from fs1 and they can't seem to send one that will work.i can't afford a new one, so will a used one work?

Hi,

Yes, a used one will work. However, you need to make sure the part number is exactly the same as the one in the vehicle. It will require require reprogramming on the vehicle as well as pass-lock password relearn. For some reason, my manual is not showing directions for these procedures. Is the ECM you are getting reprogrammed? Is the part number exactly the same as the one that was in the vehicle?
