I just purchased a 2003 350z with 93,000 miles.The previous owner told me that on a couple of occasions it would turn over but would not start. It happened to me for the first time yesterday.I started it cold and drove it 2 miles to gas station and filled it up.When I tried to start it it spun over very good but would not start.I sat there a few seconds and tried again with same results.I waited a few seconds more,put key back into ignition turn on but I paused before I tried the starter,and then it started up.I am a fair mechanic and do all my own work,but these kind of intermit.problems are the worst to find.I would appreciate any help or suggestions I could get.

+1 happens to a buddy with an '03 Track and dealer says it is probably that. Pretty sure that pulling the key and starting over resets the NATS. Expensive repair from what I have heard. Assume you are not throwing a SES light?

I lost my key and fob to my car(07 350Z). I got my spare key programmed(bought it a long time ago and just had it cut).

The next morning the car would not start. It fired up after a couple attempts.

After some reading I started to turn the key to the on position and let it beep 3 times before firing the engine, no starting issues since...........

I agree, most likely the transponder chip not being read. I've had it happen a couple times before.. Sometimes the chip gets dirt and crap in it from being in your pocket, so clean it out and try again.

Thanks for all the suggestions gentlemen.I think it is the key as some said.My son had a camero that done a similar thing.
