Well my car started up just fine this morning. Drove 20 miles to work no problem. Just go to start it and it has no juice what so ever! Wont even crank no clicks nothing. Nothing was left on. Battery is less than a year old so Im assuming its not that. The plugs arent old but not new. Opti is a year old. Im guessing alternator which has never been replace, at 95K

 

How do you know its not the battery? Do the courtesy lights, etc still operate?
Have you checked all fuses?

 

Battery, mine did the same thing, except it had some juice, but not nearly enough to start it.

 

If your head lights come ,etc, but your dash lights and guages don't when you turn on the ignition, it's your ignition switch. If you can jump start it, it's more than likely your battery or the cables. Make sure the posts are clean and that the ground wire is snug. If the dash lights and guages work when you turn on the ignition it very well may be the starter. Good luck!

 

Look at the volt gauge and see what it says when you turn the key to ON and then at START. If you can get a jump and get it started, observe the volt gauge again to see if the alt is actually charging. Then again, you might just have a loose cable.

 

Cool thanks guys. Ill try jumping it again. I tried the jump box about an hour ago w/ no luck. i guess Ill try jumping it w/ cables and something big like an truck or something. Probably just my POS battery then.
