What Are the Reasons for Difficult Car Ignition?
1 Answers
Reasons and solutions for difficult car ignition are as follows: 1. Ignition difficulty caused by carbon deposits in the car. Accompanied by slight shaking at idle speed, cleaning the throttle valve, intake passage carbon deposits, and fuel injectors can solve the problem. 2. Weak spark plug ignition energy. Not replacing spark plugs after the maintenance cycle leads to a severe drop in spark plug ignition energy, causing misfire. Many engine models today are direct-injection, requiring higher performance from spark plugs. 3. Insufficient low-pressure fuel supply. The first attempt to start fails as the low-pressure fuel line builds up pressure, succeeding on the second try. Check components: fuel pressure regulator, fuel pump, fuel filter, and internal pipelines. 4. Battery depletion. The first reaction of many drivers when the car won't start is a dead battery. The solution is to jump-start the car using another vehicle or battery. 5. Exhaust pipe blockage. Simply clean the exhaust pipe. 6. Overly rich or lean fuel mixture. Spraying cleaner at the throttle valve makes the car start more easily. 7. Incorrect engine timing. If the engine timing does not match, the engine will not start. Many car engines use timing belts. Difficult car starting is mainly due to insufficient maintenance by drivers. Car maintenance should be performed regularly and quantitatively.
