My car has been running just fine, and all of a sudden today it wouldn't start... no clicking or engine turning when I tried to start the ignition, although the dash lights and radio did come on. What should I try to get the car started/determine the problem?

 

Start with battery terminals, and maybe a jumper battery. That is the easiest problem to attack first.

 

Hi and welcome to VolvoForums.com.

What Brick850 said. If the car doesn't crank over it's likely the battery. You need to check and clean the battery connections. If it will not start when you try to jump it, you may have a bad starter.

The starter will likely need 7 volts or more to make the CLICK sound. The radio and lights may only need 3 or 4 volts. So the battery may not be all the way dead, just to dead to start the car.
