Hi i have a 06 350z and the car is having problem starting. My car starts only sometimes. It cranks but won't turn over at times. I was wondering if this is a common problem for our Z's. My friend told me it's probably the cam shaft sensor so i changed that but no luck. It's still the same. Please let me know if you can. TIA

 

need more info, this could be soo many things from timing being off, to a bad fuel pump, to a bad MAF, to a cylinder not firing
