I have a 2003 Nissan 350z with an 05 engine. Lately after driving for about 20 minutes or even at idle it will cut off and not re-crank for at least 30 minutes once it has cooled. I ran diagnostics and came back with cam sensor 1/2 and knock sensor. I have changed can sensor 1 and 2, crank sensor, fuel pump, and throttle body. I am stumped any suggestions on what else it could be. I know it is throwing a knock sensor code but not thinking this has anything to do with it. Any suggestions would be greatly appreciated.

Welcome- the first thing I'd ask is where did you buy the cam and crank sensors from? Aftermarket ones have been known to fail, so the OEM parts have been more reliable.

Unfortunately I purchased them off Amazon.

Try some OEM units purchased from the dealer or other online Nissan sales as a first step.

Even if the new parts are not throwing any codes?

Ah, you didn't mention that in your original post. Your problem certainly sounded like the symptoms of a failing cam sensor. What codes are showing up currently?

 

[DKrajacic]

Only the knock sensor or currently showing a code

What code # is showing? What kind of tool are you using?
