Why wont your car start first thing in the am but is fine all day after the first start?

It could be that the starter or solenoid is in a bind after the engine warms up. Metal expands and contracts with temperature. This is only a solution if it starts when cold which would be the first time it is started. Try starting it cold then shut it off before it gets hot then see if it will restart. If it won't start when hot maybe try replacing the starter. Hope that helps you out.
