What are the reasons why the Tiida cannot start?

[StephenFitz]

The reasons why the Tiida cannot start are as follows: Severe carbon buildup inside the vehicle's engine: This makes the vehicle difficult to start, causing idle speed fluctuations. Vehicle ignition system failure: It is necessary to check the vehicle's spark plugs and high-voltage wires. If the ignition system is not functioning properly, it can lead to this situation, resulting in idle speed fluctuations or difficulty starting. Unstable fuel system pressure in the vehicle: The fuel pump cannot properly supply fuel to the vehicle, leading to poor fuel atomization by the engine or the inability to open the fuel injectors, causing cylinder misfire or failure to start. Engine cylinder pressure deficiency: Due to time-related issues, the vehicle's engine has exceeded its service life and can no longer continue to operate, resulting in intermittent idle speed fluctuations. In this case, immediate repair at a service center is necessary. Regular vehicle inspections and maintenance are essential to prolong the vehicle's service life.
