a. Frozen Fuel Lines

If you are someone who lives in a cold habitat, you will have to drive your car in extremely low temperatures. This will cause your car’s fuel to freeze in the fuel supply lines which leads to fuel not reaching the engine. This will lead to your car not starting.

Your car won’t start if there is not enough gas in the gas tank. Sometimes your fuel reading gauge may be faulty thus resulting in it showing the wrong reading. Thus checking the fuel tank and seeing if there is enough fuel when your car is refusing to start. 

c. Clogged Fuel Filter

Your car’s fuel supply system comes with a fuel filter to filter off contaminants and dirt from the fuel before it reaches the engine. When the filter is highly clogged, fuel won’t pass through the filter, thus resulting in the car not starting.
