Citroen DS3 wont start

Without a lot more info , hard to advise ,First thing to try would check battery voltage or a jump start .

alternator good changed battery still no luck when turn key still nothing doesent even try and start some 1 said clear any codes with a diagnostic tool ill give a try see if any luck but ty anyway

Check engine is turning by hand and not seized , Clearing any codes without fixing the faults is no use . Check all relevant fuses
