What are the reasons for a car stalling automatically?
2 Answers
Car stalling reasons are as follows: 1. The use of inferior fuel (many gas stations sell impure fuel for huge profits) leading to engine carbon buildup and stalling. 2. Issues with the fuel system, including whether the fuel pump is damaged, whether the fuel passages are clear, whether the fuel injectors are clogged, whether the fuel pressure is normal, etc., these can also cause the car to stall. 3. Insufficient driving skills. A driver's lack of proficiency or improper operation can also cause the car to stall. 4. Possible faults with the spark plugs or ignition coils, causing one or multiple cylinders to misfire, leading to stalling. However, stalling only occurs when multiple cylinders fail to ignite simultaneously, so this is a possibility but relatively unlikely.
That day I was driving to the countryside when the car suddenly stalled on its own. Later, it was found that the fuel pump had failed. This situation is quite common. If the fuel supply is not smooth or the fuel pump burns out, the engine will directly run out of fuel and stall. Some friends' cars may also stall due to aging ignition coils or severe carbon buildup on the spark plugs. Additionally, if the crankshaft position sensor fails and the computer does not receive a signal, it can also force the engine to stall. Last time, my neighbor Old Wang's car stalled three times at an intersection, and it was discovered that the alternator wasn't charging, causing the battery to drain. Experiencing an automatic stall while driving is particularly dangerous. Remember to immediately turn on the hazard lights and move the car to the roadside for inspection.
