1993 Honda Civic, auto trans. Turns over but won't start. Plugs and leads recently replaced. What do we check next?

If the Check Engine Light comes on for 2 seconds and then goes out, when the ignition switch is turned to ON (Position II), then the problem is likely distributor related. Normally, replacing the Ignition Control Module (ICM) and coil inside the distributor solves the problem. If the rotor and distributor cap have not been replaced in 60,000 miles, this is the time to do it.
