Ok, for a year or so, I've had chronic problems starting, about the first 2-3 starts then would not start at all but turn over. I would have to let it sit for about a hour each time and then it would finally start, so all my research said this vehicle had a unexplained phenomenon and that people had several things replaced and no improvement - then a crack in the block mixing coolant with oil. I fixed it with Therma Gasket and it has run great since, with intermittent starting problems.
