Why Won't the Car Start Despite Having Fuel and Spark?
1 Answers
The main reasons for a car not starting despite having fuel and spark are faults in the starting system, ignition system, or fuel supply system. You can try the following emergency measures. If the car still won't start after these attempts, it is recommended to visit a 4S shop for a diagnostic computer scan to identify any fault codes and troubleshoot them one by one. The solutions are as follows: 1. Common faults in the starting system: Starter motor failure and dead battery. Countermeasures: If the battery is severely depleted and cannot start the vehicle, you can use a multimeter to test the voltage. If the voltage is less than 10V, the battery cannot start the car. Ideally, the voltage should be above 12V. If the battery is dead, you can charge it using a charger or use a jump start to start the engine. For starter motor failure, use a multimeter to check if there is supply voltage to the starter. If there is voltage but the starter does not operate, it indicates the starter is damaged and needs to be replaced at a repair shop. 2. Ignition system fault: Misfiring. Countermeasures: This may be caused by fouled spark plugs. Try removing and cleaning the spark plugs, then reinstall them and attempt to start the car to see if it works normally. 3. Fuel supply issue: Possible fuel flow obstruction or faulty injectors. Countermeasures: Place the car in a warm environment for a while, and it may start. Alternatively, thoroughly clean the fuel system. For vehicles with carburetors, check if there are any signs of loose or leaking connections at the engine interface.
