I have a 2002 E350 with the 7.3. A couple of times now it has decided not to start. Cranks fine, but won't start. Then, after awhile it starts fine and we move on. Tonight I was messing with my new obdII scanning program (OBD Fusion, still trying to figure it out), and the issue happened. When it happened, the PCM dropped and all obdII communication ceased. A couple of minutes later, after cycling the ignition a few times, my communication came back and it started fine. I also get the "service engine soon" light and sometimes a couple of other dash lights will flash.
So, a couple of questions. My batteries are a bit low at 11.1 volts. I know the PCM can be picky about exact voltage. Could this be the cause?
Or, is the PCM dying? Unfortunately, this might be a job for the Ford dealer.
