This is my first post. I recently bought a 2004 350Z. Ive had it for about 3 months problem free. Now, every now and then when I try to start the car it seems to have a problem.

When I turn the key the engine cranks and cranks but does not start. (this happens about 1/10 times i try to start the car. The other 9/10 times it starts just fine). When this happens I typically pull the key out of the ignition let that car sit for 30 secs and try again. Usually itll start then.

When I got my PPI the nissan dealership told me it needs a new battery and the 30K maintenance but no other issues. I changed the battery last night but I had the same problem this morning. Once the car is started it seems to run just fine.

Car has 45K miles on it. No know issues.

Any ideas on what it can be???

Thanks.
