I have this problem, Last winter, early spring my car has had a hard time starting..would crank but no turnover..usually on the 2nd or third time it will start. And sometimes when I was driving it would stall and I would put it in nuetral and start it again. Once summer, or hot weather came around, I never had the problem. Now it is rearing it''s ugly head again. I have done a code check, and it says the crankshaft position sensor. Could that cause it? I would have to change it when I change the oil. What a place to put it. So I would totally appreciate the help.

That could cause it. Change it.
