Your battery could be discharged enough to not activate solenoid (clicking) If it's that dead, battery may be completely shot or problem with connections. If those look ok, substitute a known good battery to see if will start. If/when does, see if charging -use voltmeter at posts with car off and on-if charging voltage will be higher when running. If charging-buy a battery.
do you have gas in the tank
your ingine will make a sound and then wont start or turn over,
Start with replacing the fuel filter.
How low is your gas tank ?
Possible battery, starter or connection problem.
it depends... it could be a starter cylonoid it could be your battery, could be a number of things does it attempt to start and wont start or does it not even make a sound when you turn the key you gotta be more specific
It may be the key, if you had one made it may not be electronic.
Make sure connections are on tight.
the alternator is bad
You need to charge your battery or get a jump. Replace the battery or have it checked because it is dead.
Check your ingnition cylinder ...
have you checked the relay on the starter? and check the wire that runs from the started relay to the starter.
