Volvo v40 t starts cold only with help

My v40 has only started very badly for a week. It’s one with gas and petrol. I did: petrol pressure regulator changed. Temperature sensor changed. New spark plugs New ignition coils throttle valve cleaned airfilter new suction nozzle cleaned Exactly it looks like it doesn’t start cold at all but you notice that it somehow wants to be very short. Warm it is a lucky thing to give gas. Under operating temperature it jumps well when I have to run on petrol on gas also not at all. Can someone help me further? In addition, it goes on gas in the standGas constantly out because I have a climate then it starts with 500 revolutions With the help of my start-up spray
