It's below zero today. Here are some very important tips: NEVER start your car just to move it and then shut it off. A cold start coats the spark plugs which cause a flood (cranks won't fire) condition on the next start attempt. After it is started, drive it at least 5 to 10 minutes until the temp reaches normal. The plugs heat up like a self cleaning oven and clean themselves. We are researching how to apply this to a kitchen. :)
The vast majority of "no-starts" that get towed in have this experience in common.
How to start in super cold: Turn key to "run" position (all dash lights on), wait a few seconds, DON'T TOUCH THE GAS PEDAL, crank the engine and let it start. Don't rev the engine, but give it a slight throttle if needed, up to 2,000 on the tach. Holding it there for a minute or two is good. Drive the car to warm it up is far better than letting it sit and run at idle.
CRANKS WON'T FIRE: Hold the gas pedal to the floor, this shuts off the flow of wet gas and dries the plugs. Crank with pedal to the floor for 15 to 30 seconds. The engine may respond with very rough running, this is one or more cylinders firing. If you're lucky, this will get it started. This trick is used by every mechanic to drive cars into the shop that have been towed in for not starting. We are lazy and will never push a car we can drive. :)
DRESS FOR A CAR THAT STOPS RUNNING. Yes, you have heat, until you don't. Sat night it was -7 degrees on my drive from Omaha to Lincoln. I saw about 20 cars either stalled on the side of the road or slid off the road stuck in the snow. At that point, you have no heat and problems from exposure are real. Don't leave home without boots or foot protection, a hat, coat and gloves.
TRAVEL BELOW ZERO-- In addition to the above, you should probably stay home if you are considering trips out of town. If you feel you must, have a way to keep your cell phone charged, a bottle of gas line de-icer, a tire inflator (12 volt compressor), a jump starter box, shovel, sand and a prayer book. :)
Let someone know when you are leaving and what is your route. Sub zero temps are a serious threat.
