The battery drained when the lights were left on overnight. So I jump started it and it fired right up. Later in the day I tried to start it and got nothing. I got the battery tested and it was fine. I took the starter out and got it tested and it was okay. We hooked up a scanner to it and we got "U0100 lost communication with ECM, PCM a". Does this mean I need to replace the ECM? I am getting power to all of my lights and stereo. Any help would be appreciated!
have the same problem?
