You need to check all your wireing from your battery to you silenoid to your starter you might have a bad connection some where. Clean the battery posts really good and the battery terminals. I fixed mine by scraping the battery post with a knife after using battery cleaner. I thought I had to change the starter, but that's all it was- the dirty post.
If there is clicking, that means the car has power from the battery so the altenator and the battery are good. I would suggest that the starter is gone bad. It will eventually grind away to where there is no clicking.
Most often this is a result of a bad battery or loose connections from the battery to the starter. It could also be the result of a bad starter, but most often its just a battery that needs charged or jump started.
change the battery every time I've had that it's been the battery the likely problem is not the battery but the solenoid that is attached to the starter motor
you need to make sure battery is fully charged, and battery cables are tight and clean the clicking sound indicates poor connections,flat battery or a bad starter motor
Could be the battery is drained or bad. Could be battery connections at battery and or starter are dirty and or loose. Could be starter solenoid is bad. Could be starter is bad.
either clean and tighten cable connections or get battery tested. if not the battery, it is the solenoid or the starter If it is clicking and not starting at first, but starts after a few tries, its your starter taking a dump. Replace it.
If it is a single click, the problem is either a loose battery cable or a faulty starter relay/solenoid. If the symptom is rapid clicking, the battery is probaly low.
dead battery bad starter solenoid bad starter loose or corroded battery or starter cables
dead battery or bad starter (with the clicking, I'm 95% sure its the battery)
Bad Battery: the clicking is the starter solenoid relay making contact but the battery is not putting out enough amps to turn the starter
If the battery is fully charged and tests okay, check both ends of battery cables to be sure they are clean and tight. If you still get only a click the starter may be at fault.
