The car wouldn't start so I had it towed to the dealership. The technician tried it and it started right up for him. They couldn't find anything wrong with it. I'm not sure if I have it right but I was told the reason it didn't start was I had the wrong type of fuel, winter verses summer. The temperature dropped after thunder storms during the night. There's been quite a few times when the car didn't start up on the first turn of the key but I didn't think anything of it. There was another time when it didn't want to start but eventually did. It was a rainy, snowy night. This last time when it didn't start it had rained also. I'm wondering if it has more to do with the rain and not the fuel.
