About a week after we bought it my wife told me she had to crank the car a couple of times before it would start and it has been getting worse since then. thank you for the advice. and more would be great.
There is no "cold start sensor". Maybe a leaky injector (flooded engine). Have you tried starting it with your foot on the floor (clear flood mode)?
