What are the symptoms of ignition system failure?

Ignition system failure manifests as: 1. Difficulty starting; 2. Engine misfire; 3. Vehicle vibration when idling; 4. Weak engine acceleration; 5. Engine failure to start; 6. Jerking during vehicle operation; 7. Engine stalling automatically. The ignition system consists of a battery, generator, distributor, ignition coil, and spark plugs. Its function is to ignite the engine for normal operation by delivering precisely timed high-voltage electricity (approximately 15,000 to 30,000V) to each spark plug in correct firing order, generating sufficiently strong sparks to ignite the air-fuel mixture.
My old car had a clear ignition system failure before. The symptoms were obvious - it took forever to start the engine when turning the key, accompanied by weird clicking sounds. After starting, the whole car would shake like sitting on a massage chair, with sluggish acceleration that responded slowly even when stepping hard on the gas. The fuel consumption also increased inexplicably - I had to spend dozens more on gas for the same routes. Later when I got it repaired, the mechanic said the spark plugs had aged and needed replacement. It was really troublesome, especially when the car stalled halfway during urgent commutes. I suggest getting it checked immediately when noticing these signs, otherwise you'll waste even more money on extra fuel costs.
