My experience, for what it's worth. I bought a 2009 500 Ri to commute to the local airport from our holiday house (no parking fees!). On cold mornings it would crank and crank without starting at all, or sputter into life and die. I can't remember where I saw the advice, but I read that the priming of the injection system is sketchy, and that the fuel pump needs several goes to get a reserve of fuel sufficient for a 'choked' start. So my routine when it's cold is to turn ignition on and wait 'til fuel pump whirr has stopped, then turn off again; repeat 3 times then hit start. Works every time so far!
