Why Can't the Engine Start?

[LaEverett]

Reasons why the engine cannot start: 1. Battery depletion—low temperatures in winter and forgetting to turn off certain electrical devices can prevent the vehicle from starting; 2. Fuel flow obstruction—this often occurs on extremely cold mornings when the fuel lines are dirty over time, and water mixed with debris blocks the fuel lines, making it impossible to start; 3. Poor ignition system performance—excessive fuel accumulation in the cylinders exceeds the ignition limit concentration, preventing the engine from firing; 4. Using unclean gasoline, especially in winter, can lead to the buildup of non-combustible gum deposits near the intake and exhaust valves and the combustion chamber, making it difficult or impossible to start on cold mornings.
