What are the reasons for the starter turning but the car not starting?

[Verona]

Possible reasons for the starter functioning normally but the engine failing to start include: 1. Presence of high-voltage spark, abnormal crankshaft position sensor or ignition coil; 2. Fuel pump malfunction, insufficient fuel pressure; 3. Clogged fuel injectors; 4. Ignition system being susceptible to moisture. Check for any of the following conditions: 1. Thoroughly inspect the fuel delivery system to ensure it provides adequate fuel to the injectors. Examine fuel supply components for partial clogs or blockages. 2. Nozzles of fuel injectors are partially clogged or blocked, or the solenoid valve is faulty. 3. When turning the ignition switch to the start position, the engine fails to start without any other symptoms. Such faults may occur due to: a) Worn-out keys or switches failing to engage the starter circuit; b) Starter relay not activating the starter solenoid switch circuit; c) Power switch not connecting the main circuit. 4. If the engine starts and runs in a warm, dry repair shop, the ignition system might be prone to moisture. When attempting to start the engine, spray water on ignition system components and wiring to check for startup issues or inability to sustain operation.
