I have had my Z for about 3 months now, and I have had difficulty starting it roughly 3 times. It just seems to randomly have trouble starting on me. It cranks just fine, but then the motor does not turn over. It takes a little time, but everytime this has happened to me, it eventually starts up after I'd say 10 times of turning the key.

Any thoughts or suggestions?

 

what year model Z? What kind of gas you put in?

 

is it a second owner?

 

It's a 2005. Bought it with 21,500 on it, and now it has 23,300. I am the second owner. I always put premium in, but sometimes the octane is rated differently at different stations. The octane varies between 92 and 93.
