You guys ever had any problems with car not starting sometimes? It seems every few days my car turns over and over and over and wont start. Then eventually it will start sounding like it barely is running then it runs normal. It runs normal and starts normal other than that, tomorrow ill be taking it to autozone to test my battery if that is ok im going to check my crank sensor I can't see anything else being the culprit.

EDIT: found this thread but no answers here : https://my350z.com/forum/maintenance...sometimes.html

 

maybe a bad starter

 

might as well have them check starter and alternator when you get battery tested. they'll do it free. i just posted on another thread about some weird crap thats been happening to my car. i just got home from autozone and my problem seems to be fixed(for now?). i had like 96 days left on my batteries warranty so i had them switch it out with a new one. i charged the old one, went up there, turned off my car, went inside for 6 mins and when i came back out to start it it just did nothing. powers up but not even a clicking sound. so i go back in and tell them and thats when they get me a new battery. i put that one in the car out there in the parking lot and start it up with a slight hiccup at first. seems it did the same thing first turn of the key...but 2nd time fired up. did that one more time when i killed it and then started up again no problems. i drove home and tried again and this time it starts first try each time. i'm still not 100% it is just my battery so i guess i'll find out tomorrow when i try to start it again. does this sound like an alternator issue? i dont mean to thread jack but there could be some similarities in our situations.

 

My car started to do the same stuff last week especially when outside temp. is real cold . It has done it a couple times.

 

Yeah everything checked out fine Im not sure what caused it but it hasn't done it in a while now so im not to worried about it. Funny thing is that it did it after I got a spare key made at walmart so im not sure if these keys have chips in them or not, I wouldn't think so but I could be wrong.

 

Do a search on "crank position sensor", it's a possibility.

 

Maybe your battery has a low "cold-cranking" value. The battery in my old car had the same problem; I bought a new battery with stronger cold-cranking amps and it was fine afterward.
