My brothers 99 7.3 computer is not responding. This is the second time this has happened. The first time it happened we though it had a bad ECM so it was sitting for about a week. Then last night I tried to start it and it fired right up. It ran all night then this morning he tried starting it and it wouldnt go. We plugged his programmer in to see if there was any codes and it said no computer response. Could this be a bad ECM?
