car will not start battery and alternator are good

If you have a crank - no start situation here are the first areas to check: 1) Fuel delivery - is the engine getting fuel? 2) Ignition Spark - Are the plugs firing? 3) Anti-theft -- are any anti-theft concerns present? 4) Base engine - is timing proper on the vehicle? Timing belt intact? Fuses and relays related to starting should be checked also. A diagnostic tool should be utilized to check for any trouble codes that are present.
