What are the reasons for no response and no power when pressing the one-button start?

[VanIsla]

The following are the reasons why the one-button start does not respond or power on: 1. The steering wheel was not straightened when parking, and when the angle exceeds 30°, the steering wheel will automatically lock, preventing ignition; 2. The vehicle is not in P gear. For automatic transmission vehicles (AT, CVT, AMT), manufacturers preset the ignition to ensure the gear is in the P position; 3. Malfunctions in components such as the fuel pump, starter, and crankshaft position sensor can all cause failure to start; 4. Excessive carbon buildup in the throttle body. When the accelerator is not pressed, the throttle body leaves only a small gap for air to pass through. If carbon buildup blocks this gap, air cannot pass through, leading to failure to start. Alternatively, try pressing the accelerator slightly during the ignition process to see if the car starts smoothly. 5. If the dashboard also does not light up, first check if the key has power. If the key is fine, the steering column lock is likely the issue. If the steering column lock is broken and does not unlock, the dashboard will not receive power. It is recommended to seek a mechanic as soon as possible to resolve the issue to avoid other unnecessary losses.
