What Causes the Inability to Start After Parking?
2 Answers
The reasons for the inability to start after parking are fuel injector leakage and a damaged carbon canister solenoid valve. Below are detailed explanations: Fuel Injector Leakage: Fuel injectors normally spray fuel, but leakage constitutes additional fuel supply. The more severe the fuel injector leakage, the richer the air-fuel mixture becomes, leading to difficulty in starting a hot engine. Damaged Carbon Canister Solenoid Valve: During a hot start, fuel atomization is normal and does not require additional fuel vapor. If the carbon canister continues to supply fuel vapor to the intake manifold, the air-fuel mixture becomes too rich, making it difficult to start. Faulty Intake Air Temperature Sensor: A faulty intake air temperature sensor results in incorrect fuel injection correction values, causing difficulty in starting a hot engine.
That day I parked my car outside the mall, and after shopping, it wouldn't start no matter what, almost causing me to miss an important event. Upon inspection, I found the battery was low on charge, probably due to reduced battery performance in cold weather or leaving the lights on. Battery issues are common faults, and corroded or loose terminal connections can also cause similar problems. It's recommended to test battery life during regular maintenance and charge it in advance during winter. Another possible cause is a damaged starter motor—if you only hear a clicking sound when trying to start the engine but it doesn't turn over, you should have a professional mechanic check the circuit or replace the part. Keeping the car's electrical appliances tidy can also reduce battery load and extend its lifespan.
