The car does not even attempt to start if it is too cold in the morning. But once it starts it has no problem starting for the rest of the day no matter how cold it is. Im leaning towards the solenoid in the starter going bad but someone had suggested the ground strap as a potential culprit as the metal can expand and contract in different temperatures, possibly moving the connection. I just had the strap mentioned to me and have not had a chance to look at the condition of the strap just yet.
Just trying to see if anyone else has had a similar problems and could offer any solutions.
Thanks!

Put a trickle charger on the battery on those cold days, go out and try to start it in the cold morning. If it fires up perfectly, it's your battery.
