What's the reason for the Elysee not starting?
2 Answers
The main reasons for the Elysee not starting lie in the engine's fuel system, electrical system, and mechanical failures. Below is a detailed introduction to the specific causes of the Elysee not starting: 1. Fuel and electrical systems: From the fuel system perspective, the main issue is low gasoline pressure and poor atomization; from the electrical system, it's due to excessive spark plug electrode gap, reduced ignition coil energy, and short or open circuits in the cylinder wires. 2. Excessive carbon deposits and dirt: Too much carbon deposits and dirt in the intake manifold change the cross-sectional area of the air passage, making it impossible for the control unit to precisely control the idle intake air volume, resulting in an overly rich or lean mixture, causing abnormal combustion or engine shaking after starting, or even failure to start. 3. Damaged charcoal canister: If the solenoid valve remains open, the mixture in the engine's intake manifold will always be in an enriched state, causing an overly rich mixture when the engine is hot, leading to failure to start. 4. Other issues: A dead battery, starter motor failure, ignition switch failure, timing misalignment, ignition coil failure, fuel pump not supplying fuel, and damage to electronic components like the crankshaft position sensor can all prevent the car from starting normally.
My Elysee also had trouble starting last winter, and after several attempts, I've summarized some experiences. The most common issue is the battery, especially in older cars where the battery has been used for a long time and loses charge in the morning cold. You can first try turning on the headlights; if they are very dim, it's likely the battery is dead. Another issue could be the starter motor; if you hear a clicking sound but the engine doesn't turn over, the starter motor's carbon brushes may need checking. The fuel system is also crucial; a faulty fuel pump or clogged fuel line can lead to insufficient fuel supply. A minor detail is poor contact in the ignition switch; turning the key all the way may not make proper contact. Lastly, don’t forget to check the car key battery, as sometimes the signal doesn’t reach the ignition system.
