Car shuts off while driving, or won't start. Just hear clicking sounds.

Because you have a few things on your car that modern ones don't check this in the dark. Trunk, Hood, and glove box lights are big offenders of this. So look from outside the car at glove box and hood, trunk light just disconnect and see if stops. One other thing is to remove positive cable, hook a test light between battery and cable. Then pull fuses one at a time when light goes out you have found the offending circuit. If anything has been added to car lately disconnect that as it may be the one doing it. This is listed under How to Repair-electrical-item9 on our site here. A volt meter will work as well but a test light is easier to see.
