What causes the 'ignition' display to show no start and no idle?
2 Answers
The ignition device may be faulty, leading to poor engine combustion conditions, requiring inspection and repair of the ignition device. Electronic pulse ignition device: Pulse-type ignition has low power, resulting in low ignition energy and spark temperature. For certain high-ignition-point combustible gases and low-concentration mixed gases, the ignition success rate is low when used with blower-equipped burners. It often fails to ignite or causes combustion accidents. Prolonged and non-continuous ignition can easily damage fuel burners. Electronic high-frequency high-voltage ignition device: High power and ignition energy produce high spark temperatures, but ignition time generally should not exceed 5 minutes to prevent overheating and damage. These devices are large, heavy, and difficult to install and transport. Coil silicon steel sheet ignition device: High power and energy produce high spark temperatures, with ignition time around 10 minutes to prevent overheating damage. These devices are relatively compact and lightweight, but domestic products generally have poor quality, with imports occupying 90% of the market.
I just ran into this issue last month and was so anxious I almost called a tow truck. When starting, the engine just groaned without firing up, and when it finally started, it seemed to gasp for breath and immediately stalled. It’s most likely a weak fuel pump, especially common in older cars—either the filter screen is clogged and can’t deliver fuel, or the pump core is burnt out. There’s also a small part called the crankshaft sensor; if it’s covered in metal shavings, the computer won’t know whether the engine is running or not. A dirty mass airflow sensor can also trick the computer into misfiring the fuel injection. Last time, I directly replaced the fuel filter and cleaned the throttle body. The mechanic used a diagnostic tool and found the fuel injection signal was intermittent—turned out the ignition coil connector was loose. Any of these issues can leave your car dead on the road, so it’s better to check early and avoid being stranded halfway.
