I have replaced both CMS on bank one and two also I had noticed that both of the electrical connectors were damaged so I had replaced those also. While replacing the connectors I had accedently crossed the wires while hooking it back up my mistake, anyway I think I have it all connected back the way it was originally, but now the car won’t even start, it turns over but it won’t start. Tried many things but, nothing it just won’t start, please help

If you’re sure you left nothing disconnected, try disconnecting the battery for a while to reset the ECU and then try starting it again. If that doesn’t work, try hooking up an OBDII code reader to see what error codes may be stored.
