I'm having a weird starting issue, and the extreme cold is accentuating it. If I let the car warm up a bit to 140 degrees, and turn it off for 4 hours or so to make sure it's completely cold (way below freezing outside), it starts up almost instantly, no problems whatsoever. But if I let it sit for 13 or 14 hours, it takes a lot of effort to start, like 4 or 5 seconds of cranking at least.

Is the engine not really cold after 4 hours in this weather? Why would the extra 10 hours of sitting make a difference? I always let the fuel pump turn on for a second or two to make sure fuel pressure is there. Do the injectors get harder to operate after sitting for longer?

I've noticed this in the warmer weather too, if it sat for a day or two between drives it became a lot harder to start than after 8 hours or so. The issue wasn't as bad though since it was warmer out.
