Hi guys, I own a 350z 2003, that will not start.
I have searched and searched.
CEL code is PU345
I replaced the sensor.
Afterwards the car took a while to start, then started. But then I left, and now same thing, cranks, but will not start.

 

what sensor?

 

Cam sensor, driver side
ok so update, realized it wasn't plugged in right, plugged it in, car started up fine.
decided to drive it around the block to make sure it was functioning properly. push it a little and car makes an explosion whoosh sound that doesn't stop. I stop car immediately and leave just incase fumes leak, letting it sit then Ill go look at it.

 

Oh man, between this thread and the how often do you end up in a street race? thread, I'm laughing my *** off here.
Not to mention the car accident into a tree and the lambo doors on 350z threads, today has been great on my350z.

 

I saw that thread lol. But why is mine so funny?
Update i,started my car and it turned right on. Any idea what could have caused that noise

 

hard to say... drive it a couple days and see what is going on, and if it still makes the noise

 

I just imagined you driving your car and then your explosion whoosh sound happening and you immediately stopping and running from your car.

 

Now imagine him in a street race when a tree hit him causing the explosion sound.
