What are the reasons for the JADE's one-button start failure to ignite?
2 Answers
The reasons for the failure to ignite mainly lie in the engine's oil circuit, electrical circuit, and mechanical faults. Below is an introduction to the specific reasons for the JADE's failure to ignite: 1. Oil and electrical circuits: From the oil circuit perspective, the main fault is low gasoline pressure and poor atomization; from the electrical circuit perspective, it is due to excessive spark plug electrode gap, decreased ignition coil energy, and short or open circuits in the cylinder wires. 2. Excessive carbon deposits and dirt: Excessive 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 volume, resulting in an overly rich or lean mixture, causing abnormal combustion or engine shaking after startup, or even failure to start. 3. Damaged activated carbon canister: If the solenoid valve remains open, the mixture in the engine's intake manifold remains in an enriched state, causing an overly rich mixture during hot starts and leading to failure to ignite. 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 such as the crankshaft position sensor can all cause the car to fail to start normally.
Last time I drove the JADE, the one-touch start wouldn't work, and it took me a long time to figure it out. The most common issue is a dead battery in the smart key—when the signal is weak, the car can't receive the command. Simply replacing the CR2032 coin battery usually solves it. Another possibility is an aging main vehicle battery, which is more prone to draining in winter, making it hard to even turn the starter. A dirty or malfunctioning one-touch start button can also cause poor contact. Problems on the engine side, like a faulty fuel pump cutting off fuel supply or a broken ignition coil, can also prevent startup. For safety, avoid repeatedly trying to start it, as this drains the battery further. It's best to call for roadside assistance and have the car towed to a professional shop for a battery and system check—getting it fixed will save you headaches.
