Greetings!
sounds like u have a bad starter. Make sure u have batt voltage on both starter terminals when cranking. If batt voltage is present and the starter is not working, then the starter is bad and will need to be replaced!

Reply to amedee's Post: well yesterday i had starter tested and they said its ok but i really feel it may be my alternator. If it help before my car started losing power here were some things I noticed was happening for example it seemed for instance when its raining and i have my windshield wipers going, radio on, defrost, and lights it would may everything go out for a second when i burn a lot of power its like its pulling something like to much power is going and mainly when i play my radio it would just go out like someone pulled the power plug

You are right! It might be the alternator! U will need to check battery voltage when the car is idling. Volts need to be between 13.5 and 14.5! If there is anything different than there is a problem! If it is within specs than your ok!

Thank u! Sorry for the long delay! Considering the cars battery is a 12 volt battery and is fully charged at 12.6 volts, 12.5 volts means the alternator is not charging at all!
