Cranks, but won't start in the mornings.

My car has been having trouble starting early in the mornings. It will start then die after 5 secs. After it dies it just cranks and doesn't start up again. I'm not sure if weather has anything to do with this, but it starts up and idles fine when it gets warm in the afternoon. Could it be an ignition coil or weak battery?

Check engine light? If so check your codes.

Off the top of my head, this symptom sounds like your main relay/fuel pump relay.
