My car will not start, just clicks?

The battery does not have enough charge to start the car.

The noise you hear (if it is click click click and not just one click) is the starter starving for power. Your battery's charge is less than required. The problem is most likely your alternator. It is not charging your battery and the hesitating is caused from lack of juice to your ignition. Probably when you step on brakes or use up voltage in any of a number of ways. Charge the battery with a charger or 15 mins with jumper cables then head straight to your repair man or walmart. Have your charging system tested and repaired or test it yourself with a volt meter. If it reads above thirteen volts with engine running and headlights on its good if it reads 12.5 or less turn off car and check again. if voltage is only a few tenths of a volt from running voltage you need an altinator.

I no longer have this car but the problem ended up being in my emissions system. Had nothing to do with battery or alternator.

I hate to break it to you but the emissions system wont keep your car from starting, whoever told you that is full of bullhockey.

I am sorry sir but the clicking you described is caused by low voltage to the starter solenoid. Your batt may have had voltage but was it enough? If so you may have had a cable issue and I hate to be the rain maker but if your car wont run you don't have any emissions. Furthermore nothing in the emission catagory would cause your problem

Throw in a new battery, try it if still not starting tap starter motor with a wooden handle hard and try again, tap it with key turned on, solinoid could be stuffed.

You may have a low battery , turn on the headlights , are they bright ? do they dim when you
try to start the car? if not probably a starter ,if not check battery connections

Thank you. I no longer have this car but it was a good one until I started having little problems popping up here and there. Could not find a good mechanic that didn't try to screw me every time I turned around.
