Check the battery voltage, ensure the wiring is in good condition, and verify that the starting circuit is functioning properly. Check whether the gear is in N or P position (for automatic transmission vehicles). Turn the ignition switch and observe if the starter responds. If there is no response, focus on inspecting components such as the relay, brushes, and coil. Check for any leaks outside the engine, ensure the wiring and pipeline connections are intact, and inspect the crankcase ventilation system hoses for leaks or cracks. Verify the proper functioning of the high-voltage wires, ignition coil, distributor, and electronic ignition unit. Use a diagnostic tool to read the fault causes corresponding to the fault code, then proceed with troubleshooting one by one.
