What Are the Reasons for a Car Starting and Then Stalling?
2 Answers
The reasons for a car starting and then stalling are: 1. Triggering the car's anti-theft system, causing the engine to lock; 2. Faulty ignition switch; 3. Damaged ignition module or damaged ignition reference signal line from the ignition module to the engine computer; 4. Low fuel pump pressure, fuel line leakage, insufficient power supply current, damaged fuel pressure regulator; 5. Carbon deposits in the engine. The solutions for a car starting and then stalling are: 1. Check if the car's anti-theft system is triggered; 2. Inspect the working condition of the ignition switch; 3. Check if the ignition module and signal line are faulty; 4. Examine the fuel lines for leaks; 5. Clean carbon deposits from the engine; 6. Check if the battery has sufficient charge.
I used to frequently encounter the issue of the car starting and then stalling, especially in older vehicles. The most common cause is a fuel system malfunction, such as an improperly functioning fuel pump, which leads to insufficient gasoline supply and causes the engine to stall. Another possibility is a clogged fuel line or a dirty fuel filter, preventing fuel from flowing properly. Another potential issue lies in the ignition system—dirty spark plugs or a faulty ignition coil can prevent the engine from starting, leading to stalling. If the idle control valve is stuck and cannot maintain idle speed, this can also cause the problem. Cold weather exacerbates the issue, as insufficient engine warm-up makes stalling more likely. It's advisable to check the fuel level before driving, ensure it's not too low, and quickly inspect ignition components. If any issues are detected, prompt repairs can help avoid risks on the road.
