My car does not start

What is your question?

I had just pass smog and after 2 days the service engine light came on. The next day when I try to start it would not start. I thought it was out of gas. I put gas and nothing. After I checked and change a few fuses. Fully charged the battery. I stared. got a full tank now and next day again it would not start.

How long has your 2002 Chevrolet Express 1500 had this problem?

Just a few days. After I had it smog only 2 times would not start.
