Car won't start!...and it's not the Steering Lock...

ghostbusters

But I can confirm in my australian 2013 370Z that the issue comes from the clutch interlock switch that was shown on page 3 of this thread. Genuine replacement parts are coming from Japan which will take 4-6 weeks but it was only Aud30 or so. The mechanic has cleaned the two connecting rods thing in the switch and car starts up now without any hesitation.

Some final notes:
If you're experiencing the constant cycling between lock, ACC, On and off without anything else happening, this clutch interlock switch is probably dieing.
If you're having slow cranking, consider a new battery with a minimum of 582 CCA. I went with PowerSonic PNS70LMF batteries at my local Bridgestone Tire Centre and it fits fine in the battery compartment. MIND YOU, the car needs constant power even when swapping batteries, otherwise you'll have to factory reset the ECU at your local Nissan to get the windows to close up when you close your door.
Not much I can say about the steering lock mechanism except that you should have power steering function i.e. no steering lock when the car is on ON, otherwise get that checked.

Hope this helps!

First, let me say I am very happy you got your issue sorted out

But the statement above is a bit ridiculous. Just make sure windows are down when you swap batteries and do the window reset procedure after. There is absolutely no need to go to a dealer for a factory reset of the ECU

I just had to replace mine the other week. I did it in the auto parts store parking lot with no issues.

Experienced this a few weeks ago for the first time and didn't experience it again until this weekend. Driven for a couple days now and it hasn't happened again. I haven't cleaned or replaced it yet.

Don't know if this is attested to when the clutch and csc was upgraded to the Z1 clutch, flywheel and elim kit (which is awesome) or the clutch pedal being adjusted and helper spring removed or it going from 30 degrees to 80 in a week or it just plain being dirty as mentioned. So, there's that for a run on sentence.

Already experienced the luxury of the steering lock and csc failing haha. Fun times =)


Went ahead and ordered the clutch pedal switch and plan to replace it.
