Check your owner's manual. At the back of the engine compartment there is a little plastic "box" with a "+" on it....open the box and the nut inside is your positive terminal. On the driver's side, about 1/2 way back near the round suspension rubber is a seemingly useless bolt...this is your negative terminal. The battery is in the trunk.
Try the battery.
