I replaced the alternator now the car won't start. All wires are connected and the battery is good but the car has no spark at the plugs.

Try checking the crankshaft position sensor connector if its loose or disconnected-start here

The crankshaft sensor is pluged in and wires are good also the check engine light does turn off when cranking and the security light goes out when the ignition is on.

You need to backtrack everything you have touched while removing the alternator if it was running before you replace the alternator
