HELP! Car doesn't want to start randomly
 

I just got my 2006 G35 sedan used from a dealer on saturday 2/5/11. Every once in a while, the car doesn't want to start but it turns over. This is very random though, I checked the battery cables, secured. I checked the oil and coolant, nice and full. I'm running a full tank of premium gas, so I don't think that would be it. Any suggestions? Electrical maybe?

prolly the cam sensor(s). extended cranks when it does decide to start up? no codes or lights?

codes? mods? miles? at/mt? more info will help with us give you more help. :) But congrats on the new car and welcome :)

neither codes nor lights come up. i have no put ANY mods on this car, nothing aftermarket either. im quite confused but thank you! :) i love this car but i want that to go away first lol. yes extended cranks, about 4 or 5 times, but i have to wait a little bit before the last one. oh and its only at 42000 miles....
