Dead battery low battery will click check all connections for tightness If battery is charged and still no response starter for sure.
Jumping a Fully Charged BatteryIF the connections [jumper cables] are connected properly, then nothing out of the ordinary happens. Connecting a jumper battery or power axillary power source only makes additional current available, if the starting circuit needs it. If the batteries are connected properly [in parallel] then this procedure increases the cranking Amps available and the voltage remains the same.
Check for loose or corroded battery cables Check trigger wire on starter (small wire) for corrosion (common problem) Bad starter solenoid
starter

gas or a battery charged car makes a car run.
If it does not start and just makes a clicking sound, this is an indication of: a low battery, poor battery connections, or a defective starter solenoid ( next to the battery hooked up by the short positive battery cable). Check and clean your battery cables first , then look to the solenoid if you know the battery is fully charged. I hope this helps you. Mark
The clicking can signify a weak or dead battery. Make sure the battery is fully charged to start the engine.
