Why is there no response when turning the key to ignition?

[McGarrett]

No response when turning the key to ignition may be due to electronic or fuel system failures. Below are detailed explanations of the causes and solutions: Electronic failure: The occurrence is usually very sudden without any warning signs. Possible circuit failures include: blown fuse, open circuit in high-voltage coil, open circuit in low-voltage circuit, detached central ignition wire, distributor rotor leakage, or damaged spark plugs. Electronic failure mainly refers to the malfunction of the central computer control board. Solution: Inspect the central computer control board, identify the issue, and replace it if necessary. Fuel system failure: Engine stalling caused by fuel system issues often comes with symptoms like weak engine power or a spongy accelerator pedal. Possible fuel system problems include: fuel pump failure, blocked fuel lines, clogged fuel filter, carburetor malfunction, or damaged injectors. Sometimes, the fuel tank might be empty without the owner's awareness. Solution: Check the fuel system for issues and promptly perform cleaning or repairs.
