i have a problem with my car starting. it will start as long as the check engine light is on and it runs fine, but when you turn the key on and the check engine light doesn't come on, the car won't start ,and it will come on whenever it feels like it, some times it will start after about five minutes or so and then sometimes it won't start all day, and then you can start right away when you first get in it ,it does crank when you turn it on but it won't start ,any info would be appreciated thanks
