just an addition to others-
first try an alternate batter jump starter to start the car....
that clicking sound is most likely a problem with your starters solenoid-----
(only on a quick fix, not to do this every time)- but you can go under the car spot the starter and tap the solenoid every soo lightly and try to start your car again afterwords- itll start.(tapping it would help give it the extra jolt to get it to turn over) but be care full doin that shiot. this is usually done with cold weather situations on a very cold engine/car though- but can also be done to get you out of a rutt!
If you try to start it, the starter motor does not work at all but the solenoid clicks, then the problem is with either the battery, the starter relay (-if equipped-), the main solenoid contacts or the starter itself (or the engine is seized). surely your engine is not seized so yeah..
If you are hitting the starter and it's working.... its not a relay issue. Just drop the starter and take it to the store for a new one.
cheers and gl-
