Have a 2012 Nissan Vera hatchback.

Went yesterday to start car after not starting it for a week. Would not start for about 15 minutes, then finally started!

1. Battery strong
2. No warning lights or codes
3. When finally started ran it smooth; no miss.
4. Tried starting car by putting the accelerator to the floor; made no difference.

How do I trouble shoot this? Where do I start?

Would a can of dry gas help? How about fuel injection cleaner?
