Swift dzire Vxi 2016 model Starting problem

Hi,

My name is Ashok N K . From the past 4 to 5 months ,I am facing typical starting problem in my Maruti Suzuki swift Dzire Vxi 2016 model . The problem happens when the car is kept idle for the long time of 5 to 6 hrs , while starting the Engine the cranking will not happen immediately. There is a delay of around 10 secs .
But after first time try , the car will start immediately with out delay .

Maruti Suzuki Mandovi service center @ Basaveshwara nagar recommended to replace Battery and the same replaced , but still same issue .The below activities done by the service center .
1. Fuel tank and filter cleaning
2.chemical cleaning of injectors done
3. Throttle body cleaning done
But after done all the above , still car behaving in the same manner . .

Please suggest .
