What to Do When the Car Engine Won't Start?

[MacBrayden]

Car engine won't start? Here are the possible causes and solutions: 1. Fuel flow obstruction: The main characteristic is the absence of fuel pressure in the engine's fuel supply line. This situation usually occurs on extremely cold mornings due to long-term dirt accumulation in the fuel line. At very low temperatures, water and debris can mix and block the fuel line, preventing the engine from starting. In such cases, an emergency solution is to move the car to a warmer environment, and it should start after a while. Alternatively, thoroughly cleaning the fuel line can permanently resolve the issue. 2. Spark plug clogging: If the vehicle manages to start despite clogged spark plugs, it will run roughly. The first step is to check the engine's condition. If irregular shaking occurs, it's likely caused by the spark plugs. Inspect the spark plugs for any issues and replace them if necessary. 3. Fuel pump pressure leakage: After prolonged use, the fuel pump may experience wear, leading to reduced fuel supply pressure and difficulty in ignition. Replacing the fuel pump can solve the problem.
