2003 g35 coupe 6mt.
The car was bought in South Florida, then taken to Colorado, then back to FL, then to GA and back about 3 times within the last 2 years and the battery was changed before coming to FL from Colorado.

Ok a few weeks back I checked my battery at an Auto Parts, they told me the battery was fine (it's a duralast and is about a year and a half old).

Yesterday, when I went to start up my car, I heard a click and no sound. I tried again and heard the engine trying to start but nothing. Tried again and it took a bit but the car finally started. It's been about a year since the car takes longer to start up.

The same day that I checked my battery at the Auto Parts I asked them to check the engine light I had on and they told me it was a camshaft positioning sensor and that it may be the reason why it takes longer to start up because not enough volts are going to the starter.

Yesterday I went to check my battery at a parts oreily and they told me the battery was bad and needed replacement.

Today I actually went to a car shop and was told that the battery was fine and that the problem was a sensor in the clutch when you push it in to start the car.

I've read related topics but everyone has a different answer, I never stall the car and never have had a problem with the battery. I do have two 12" subs in the truck (barely fits in lol). I've read that it could the radio but it's an aftermarket pioneer.

Someone please give me an answer!

I forgot to mention that the car works perfectly fine and it does end up starting after the 2nd or 3rd try also I'm in Georgia at the moment and temperature is usually in 40s 30s when I get out of work and 50s 60s whem I leave for work (only times I use the car cuz I work 12 hr shifts all night) and I always let the car warm up as necessary before driving it. Never listen to music while I'm not driving it either.

 

Not an audio/video related question, moving to a more appropriate forum.

 

Someone help? Today my car just turned off while driving then started up again on its own and later that night it turned off on a turn. I had to turn it on to stop in time and not hit the truck in front of me

 

Youve got a short somewhere. Check the wiring for the AMP and everything connected to the battery. It really sounds like the wire is shorting out and causing your battery to discharge. I would trace every wire coming off the battery and make sure it isn't touching anything or loose.
