No cranking at all. All the dash lights come on and I can hear the engine fan come on. The Cam Position Sensor was replaced a couple of months ago but this problem was there before and after. Not sure how I can check the park/neutral safety switch. I've shifted the car with the key in/on from park to every other gear and back again many times when the car wouldn't start but that did not correct the problem. Is checking the park/neutral safety switch something that the dealer should look at?
