Needing Some help car won't start
 

I recently purchased a used 2003 350z enthusiast. About a week ago right when you start the car it made a ticking sound then it went away after a couple of seconds. A code P0011 intake valve timing solenoid came up shortly after that. Then I was headed out of town I set my cruise control and I got about 35 mile out of town then my car just dies. I tried to start, it would turn over but not fire. I was less than 1/4 tank so I thought the gas gauge was wrong. So I went and had it towed to a gas station filled it up, same thing crank but won't start. Got it home, ran the code reader this is what came up: P0340, P0345, P1615. 0340 and 0345 are camshaft sensors, so I installed new ones still won't start.

The P1615 code that your engine has thrown is to do with the NATS system which is probably why your engine won't start as the immobiliser has possibly kicked in allowing your engine to turn over but not fire up.

Sorry to hear about your ordeal. But that many codes popping up in a relatively short time is definitely NOT normal. I'd say this is a case where you need a trained factory tech with a CONSULT III unit running diagnostics. How many miles are on your '03?

138,000

Mileage isn't that high, but with an unknown history, I'd take it in. This isn't something that's going to get solved on an Internet board.

Volts gauge
 

Just for thoughts, what does the voltmeter say? When I start the Z it is around 12.5 volts. Your battery needs cold cranking amps to start it. Is it a battery issue? Does the alternator alternate? Just putting the obvious out there. :dunno: Do you have any jumper cables and someone willing to jump start with a ground on the engine (positive + battery post)?
