IF you have fuel and spark, it should run unless the spark is too weak or the fuel pump pressure is too weak. Check for a hot blue snapping spark at the plugs. Also, check fuel pump pressure. If the check engine light was on, there should be a trouble code stored in the computer that will direct you to the problem. Most parts stores will scan it for free, but since it doesn't run, ask if they will rent or lend you a scanner.
