Problem starting on cold days

[strk500]

My explorer seems to crank a few extra times on a cold start when its below 30 degrees. After it does start, it wants to die but doesn't then the revs even out and its fine... any idea wat causes this??

It might be a few things such as the engine coolant temperature sensor, air charge temperature sensor, fuel filter, or fuel pressure regulator.
