When your car will not start on a cold morning, there is always the possibility of a frozen fuel line. A fuel line freezes when water condensation builds up in the fuel line. If your car is left out over night and the temperature drops below freezing, your fuel line might freeze.

Your Car Will Not Start

No matter how many times you turn the key in the morning, the car engine will not turn over and actually start. While this can be extremely frustrating, you may want to wait until the sun has been up for a few hours and try again. If the car starts fine in the afternoon but not in morning, you may have a problem of fuel line freezing.

Winter Temperatures

If your car is normally parked outside during the winter and the temperature drops below freezing, be aware this could freeze your fuel line. If you are not using some kind of fuel treatment to prevent condensation in the fuel line, and your car will not start in the morning, your fuel line has probably frozen. There are additives to protect your fuel line, but the best practice is to keep your car in a garage so that when temperatures drop below freezing, your car will start in the morning.

Water in the Gas Tank

A larger amount of water in your gas tank will cause your car to buck and stall. The water will freeze in your gas line and cause the car not to start. If you take a sample of the fuel from your tank and have it checked chemically, you may find a high water content. You can separate the water from the gas (it will not mix), then reuse the fuel. You may have to put a fuel additive in the car to protect it from water. If you have a newer car, the tank should never have water in it. The tanks are sealed and pressurised to prevent this problem. If water gets into the tank, you may have got watered-down gasoline.
