What would cause my car not to start at all??

I replaced the battery last year and tried charging it by borrowing a charger from Advance Auto. It started out slowly cranking but then will do nothing now. Its been doing this off and on but it always ends up starting. This time it will not turn over at all. Could it be the starter?? I know its not the alternator because I just had that replaced.

Well lets start out by saying the alternator only keeps your battery charged when the car is running. (if it works)


If you have a one year old battery why was it needing a charge?


Ok. Lets check one thing first. Even with a bad battery you can do this. unplug the coil .Take your spark plugs out. and see if the engine will turn over by hand or by cranking with starter motor.


Ok. If the motor turns over by hand or by the starter then the motor is not frozen. Could be you have low water level in battery and you need to refil with distilled water. Then charge battery. You then should be good to go. Other reasons could be timing belt slip. Bad coil. Bad alternator not charging battery. Bad battery etc.

Are the terminals and cables clean? or is there %26quot;salt%26quot; on them? if there is %26quot;salt%26quot; ( corrosion) then clean the ends up.
Reply:maybe the battery is not taking charge, like a dead cell.
Reply:Chronic undercharging is one of the prime causes of premature battery failure. If you only just had the alternator replaced, then it must have been undercharging your battery, for who knows how long. Also, if you were sold a battery that is not matched very well to your car, the parasitic load (security system, radio presets, ECM computer, etc) could be leading to chronic undercharging and again (you guessed it), premature failure.





I%26#039;m not saying your battery is bad -- just that it might be bad in spite of being practically new.





Go to any car parts store and ask them to %26quot;load test%26quot; your battery. That%26#039;s the definitive test. If you take it to place you bought it from they%26#039;ll probably replace it free within a year if it tests bad.





Once you %26quot;know for sure%26quot; that your battery is ok, determine whether enough power is getting to the starter. With a multimeter, measure the voltage from the starter main terminal to engine block ground with the starter turned to %26quot;start%26quot;. If you get 12+ volts and the starter isn%26#039;t turning the engine over, replace the starter. If you don%26#039;t get 12 volts, you%26#039;ll have to troubleshoot the keyswitch and wiring harness.
