Help car wont start, Batt problem Options

[azian_advanced]

one thing you should do is clean the battery terminals.. use some sort of wire brush and clean the power and ground connectors that attach to the battery and the terminals on the battery itself. there's a chance that this may be the culprit.
i had this issue in the summer, my battery and alternator were in excellent condition but my car wouldn't start after turning it off. the problem was it was not getting connection due to a layer of oxidization that develop between the connectors and the battery terminals.

Get a voltmeter check your battery. It should be around 12. Then jump the car if it doesn't start and when it does check it again. It should be around 14 or higher. If not and lets say its 13.8 and it slowly drops then its your alternator.

Yeh when the car is on and im driving it doesnt die. Only when its off and i turn it on. Thing is its got a new battery 5 months ago. . . Well ive jumped it and going to leave the car on for 15mins and turn it off and turn it back on to see if its going to run. If not something is up

Alright the car was on in my driveway. . and now it just turned off itself. =/

Get your batt tested even new batts can have problems and be defective too and if the batt tests good its your alt its probably faulty and not charging your batt at all.

well that has happen to me alot lately.. check your grounds. if all your lights and stuff turn on and radio works but once u try to start the car and all your power just dies and the car wont turn. i think it might be a ground. i had to hook up a 10gauge wire to my starter bolt and chassis. once i did that, my car turn over right away. i would suggest doing that and see if it starts.
