Cam sensor if the ecm doesn't see rpm's via the cam sensor it doesn't know you're cranking it.
You can crank it till the gauges come up and see if it reads rpms to diagnose. Had one go intermittently bad on a 3406E, it would randomly die no codes as the engine dosen't think its running. Finally cranked it till tack booted up and it had no signal 0rpm, showed 200rpm with the cam sensor working. This was on an international that only used one sensor for cam/engine speed.
