Turns over but doesn't start
 

2006 350z turns over and will not start in the morning. Have been able to get it running after trying each day about 5 times. Then it starts up he rest of the day just fine. Temperature in the high 60's at night so dont think this could be a problem. Not sure what to start checking....any suggestions????

NATS/Immobilizer?

any codes?

no codes....if it was the NATS/Immobilizer would it still start? it does start after trying 3 or 4 times in the morning then no trouble starting it the rest of the day until the next morning.....thanks for the help I appreciate it

Could be vapor lock. Has it been humid in your area recently? If not, then make sure your air filter is clean and your fuel is not old

Sometimes I have a NATS/Immobilizer problem. Where the transponder in my key can't be identified by the car. It will crank over but wont start. The security light on the dash by windshield will stay solid RED if your key can't be read. I usually pull my key out and put it back in and it will start...

Next time it doesn't start while cranking, see if security light stays on solid red.
