I did get a new code this morning, P0336B, which related to the 24X crank sensor. Which I read a bunch of different places will not cause a no start situation. This is the first time I have seen this code. Is it possible that it's confusing the PCM enough to not open the injectors enough to start the car?
this type problem sounds like a bad temp sensor/or wiring of it. if the pcm gets the wrong temp from sensor then the engine will have start issues. if the sensor is open then the temp reported would be -40 deg f .. or if shorted a hot 250 deg f temp that would reduce the fuel injection so that a cold engine will not start.
