I had shut off my Altima after a short trip. When I went back out 1/2 hour later, I had difficulty starting the car. I went to the store and was in for approximately an hour. When I started the Altima, it was again difficult to start but then the service engine soon (SES) light came on and now stays on. I do not have difficulty starting it now but the SES light stays on. I checked the gas cap and it was secure. Car has 63,000 miles on it. Tried to get the code but was unsucessful.

 

It did it again. Can anyone give me any advice?

 

Oh , by the way , it is a 2.5 4 cyl , 5 sp man.
