I have a 2006 Nissan Xterra with about 106,000 miles on it. For some reason, the car doesn't always start. I will try to start the car, and I can hear it attempting to start but it never does. Additionally, it almost always starts on the second attempt, if I wait about 20 seconds with the key out of the ignition.
I have recently replaced the battery, and it hasn't made any effect. There are no check engine lights on. When the car runs, it runs seemingly ok. There's no correlation between the cold or hot weather. It has been doing this in the winter, as well as the past summer.
Where can I start looking to diagnose this problem?
