Remember you all have brand new engines which are still tight, also the weathers not warmed up yet... after the summer you should be ok.

Just keep the key to the start position a bit longer than usual to see if that helps. My focus does the same sometimes.

Also if it doesn't start, make sure you sit and wait for 10seconds to allow everything to sort itself out in the engine and make sure you dont flood it.

Just take care of your engines guys, they are still brand new remember!!!
