Yesterday afternoon i drove the car around 2pm it drove fine running like normal. Around 4pm the car would not start, The car turns over but will not stay running. There is a white smoke coming from the exhaust and smells really rich. I'm just lost and have no clue what the problem could be, to me it seems like a fuel problem. The car is acting like it's getting no fuel, any help would be great. The car itself is a 99 w/130k w/ regular maintance.
