What Are the Causes of Engine Stalling?

[AllisonFitz]

The following are the causes of engine stalling: 1. Crankshaft and sensor failure: The crankshaft position sensor's own resistance value is abnormal, causing the crankshaft speed signal to disappear after the engine warms up, leading to engine stalling; 2. Fuel pump failure: The fuel pump's resistance value changes after prolonged operation, failing to provide normal fuel pressure, resulting in engine stalling; 3. Ignition system failure: Malfunction in the ignition system or overheating of the ignition module prevents normal operation, causing engine stalling; 4. Throttle failure: Abnormal throttle signal voltage leads to engine stalling while driving; 5. Wiring issues: Loose connections causing intermittent engine stalling. The methods to address engine stalling include: checking if the fuel tank has sufficient fuel; inspecting whether the filter is clogged; examining if the battery is supplying power; and verifying if the fuel pump is delivering fuel.
