Hello my fellow 350z owners! About a month ago, I purchased my lovely 2003 Track Z, MT. It had 99,000 Miles on it but I have then since put 100,413 on it. About 2 weeks after buying my Z, I have had this startup issue. The following video I took will show you exactly what I have been experiencing.


I have tried searching the forums for this issue but I have been so far unsuccessful. Maybe I just suck at searching, but the video should explain everything. I'm not quite sure what brought about this issue. I should have shown the battery voltage meter but I assure you it's always within acceptable range. Right between 12 and 16. And yes, my foot was all the way depressed on the clutch and there is no rug or anything else blocking it. I appreciate any insight anybody can shed on this!

 

I'd guess the switching mech in your ignition key lock is faulty.
Have you tried to wiggle the steering wheel?Do you have another set of keys?
Possible the code off the key is malfunctioning?

 

Checked the clutch disengage switch?

 

Have you tried jumpstarting it and see whether it works?

 

Yeah, that's a good idea if you can.

 

Wondering if you fix your problem yet? I think it is the NATS problem!!!! I am afraid I will face this problem one day too! I searched and it said it might be the NATS antenna problem! I want to know just replacing the Antenna without getting a new BCM and key fixed this problem???
