Is No Response When Starting the Engine Caused by Spark Plugs?

No response when starting the engine could be caused by spark plugs, but it may also result from carbon buildup in the car or fuel injector leakage. Carbon Buildup in the Car: This failure to start is primarily due to excessive carbon deposits in the idle speed motor, intake tract, intake valves, and combustion chamber. When there is too much carbon buildup or dirt in the intake tract, the cross-sectional area of the air passage changes, leading to an overly rich or lean air-fuel mixture. This causes abnormal combustion or engine shaking after starting, and in severe cases, the engine may fail to start at all. Fuel Injector Leakage: No response when starting could also be due to issues with the fuel injectors, such as leakage or excessive carbon buildup, resulting in a lean air-fuel mixture during startup and making it difficult to start the engine. Additionally, if the charcoal canister or the charcoal canister solenoid valve malfunctions, it can also lead to difficulties in starting the engine.
