What are the reasons why the Mazda CX5 one-button start cannot start?

[McEden]

Mazda CX one-button start cannot start due to damaged spark plugs and burned distributor contacts. The following are specific explanations for the above reasons: Damaged spark plugs: Open the hood, lift the engine's plastic cover, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. During removal, check for leaves, dust, etc., outside and clean them thoroughly. Insert the new spark plugs into the spark plug holes, hand-tighten them a few turns, then use a socket to tighten. Reinstall the removed high-voltage distributor wires according to the firing order, and finally, secure the cover. Burned distributor contacts: Insufficient ignition voltage from the car's spark plugs can prevent the air-fuel mixture from burning in time. Incomplete combustion of the mixture can form carbon deposits in the engine's cylinders, causing the engine to overheat and affecting its normal operation. Therefore, regular maintenance and inspection of spark plugs are essential. When spark plug issues are detected, they should be promptly replaced or repaired.
