What Causes a Car to Suddenly Stall and Fail to Restart While Driving?
2 Answers
Reasons why a car suddenly stalls and fails to restart while driving: 1. Electrical circuit failure: This can cause the car to stall due to a low-voltage power interruption. It is recommended to check the ignition and starter switch, as well as the fuse box. 2. Low-voltage circuit short causing stalling: In this case, the car stalls intermittently. The low-voltage circuit should be inspected. 3. Component failure: This may involve the ignition coil, capacitor, or electronic ignition module. 4. Fuel system failure: Possible causes include a damaged fuel pump, ruptured fuel line, clogged carburetor fuel inlet, or an empty fuel tank. 5. Ignition system failure: Issues such as engine overheating or problems with the anti-knock system can also cause the car to stall.
Last time I was driving on the highway when my car suddenly stalled. I tried starting it several times but it wouldn't fire up, which left me flustered. After calling a tow truck, the inspection revealed the battery was dead, possibly because the alternator failed to charge it. It could also have been a faulty fuel pump not delivering fuel, or problematic ignition coils failing to spark. A broken belt can also cause the engine to stop. It's crucial to immediately turn on hazard lights and pull over after stalling to avoid rear-end collisions. Now I regularly maintain and check the battery and fuel system to prevent this from happening again, and I keep a portable jump starter in the car for emergencies. Another friend experienced stalling due to a clogged fuel filter, which was resolved after cleaning. Older cars especially require attention to these details.
