Car goes click click when you try to start but turns over with a boost?

The battery does not have sufficient voltage to start the car when it's cold. Have the battery checked out. If it still goes click click after running the car for a while, have the alternator checked also. A bad battery will not hold a charge and a bad alternator will not recharge the battery, (That is the reason to have the battery checked first).

Make sure the connections at the battery are clean and tight.
