Q: Won't start periodically

asked by on November 12, 2016

03 Caravan will run great for a week or two then all of a sudden it'll turn over but won't start.After multiple tries almost killing the battery it'll finally start and white smoke will pour out for a few min then clear up and drive fine for a few more weeks then happens all over again. I have had a few guys tell me that's it's the 02 sensors or the pcm control module. Any help would be appreciated.

My car has 240000 miles.
My car has an automatic transmission.
