The reasons for the clicking sound when starting the car and failure to ignite: Fuel system failure: Mainly caused by fuel switch (no fuel), fuel filter (blockage), carburetor (no fuel or overly rich mixture), or bent fuel pipe. Electrical circuit failure: Short circuit in the vehicle's electrical components (such as ignition switch, ignition coil, igniter, magneto, etc.), or loose wiring harness connectors causing an open circuit. Cylinder failure: Insufficient cylinder compression, improper air filter element intake resistance, or engine intake/exhaust system issues. Fuel system issues: First, disconnect the fuel pipe under the fuel tank and connect it to a mineral water bottle. If there is a continuous flow of fuel, the fuel tank is not blocked. If blocked, remove the entire fuel tank, pour out the fuel, rinse it with a high-pressure water gun, and let it air dry for a few days.
