It could be the starter interlock/immobiliser relay. Last post but one.

I would suspect the check valve in the fuel pump. When it goes, it releases the pressure in the line so cold start ups take a few cranks to run the pump and pressurize the line.

Thanks a bunch for the link. It seems to be the exact symptoms I am experiencing. I told my mechanic to check for that already.

Thanks for the tip, I will have my mechanic check into this as well.

So apparently it was a faulty fuel pump which got replaced. But I am not exactly sure if that solved it. need to let the car sit for some time to test it out.
