Cranking but doesnt start, or intermittently not starting

My car does the same thing...sometimes it wont start....have to turn the key off then when I crank it again it fires right away. Possible that the in tank fuel pump pressure regulator isn't building to the proper pressure. Nissan did post a recall....under warranty *recall* I might add.... there is an updated pump that will cure the problem but since you most likely are out of warranty it will cast $400+ for the part plus labour if you can't install it yourself. Call nissan to verify if your car is affected by referencing your VIN with them. Dave.
