My car refuse to start on 2001 Infiniti I30

My car will not start until after several attempt. Sometime it will start as soon as I turn on the ignition sometimes it won't. When it runs for let say 10 minutes and I turn off the ignition and I try to start it again it won't start until several attempts. Can you please enlightened me on this issue.

Really need to scan the computer systems on your Infiniti. I just replaced the Cam Sensors on an Infiniti with similar symptoms. There was a Service Engine Light on with trouble codes for the Cam Sensors. I replaced both Cam Sensors, now the car always starts in a snap
Wow, I forgot to mention service engine light part and it is on. Dandd you are a real master, you nailed it. Do you know how much it will cost me to change both Cam Sensors?
