zero610,
My starting problem seems to happen most frequently after the car sits for about an hour or so, usually after it has reached operating temperature with normal driving. I have not experienced any cold starting (first thing in the AM) problems. It only happens after I drive it and it sits for a while. I picked my car up from the dealer yesterday, they replaced the fuel pump. There is a strong odor of gasoline in the car (hope that is normal after a fuel pump replacement). I drove the car for about a 1/2 hour, let it sit for about an hour...same problem, hard start (long cranking - then sputtering as it tries to start). The car always starts - my concern is the excessive wear on the starter. I'm not a mechanic, but the problem doesn't seem to be the fuel pump
unless they replaced it with another defective one. I'm going to take it back and have them look at it again on Monday. I have about 7000 miles on the car. I have had the 370Z for about 1.5 years (I travel alot) of a 3 year lease. I'm pretty disappointed that I'm having these problems with a car I don't drive that frequently. I may be crossing Nissan off of my list after this experience.
