Just noticed an issue this week. After I've been at school all day (teaching), when I attempt to start my car it will crank but not start until after couple of attempts. I have no problems in the morning, but my car is garaged at night. I already arranged for a service appointment next weekend, but I figured I'd check here for the heck of it. After the first instance, I double-checked today to be sure I wasn't leaving a door cracked or left on any interior lights. I hadn't. It has only happened on these two occasions, but both in the past few days. I want to note also, I live in Sacramento, California so we're not talking Arctic cold here.
