What are the reasons why a car cannot start after being parked?

[VonZane]

Reasons why a car cannot start after being parked: 1. The water temperature sensor is faulty, in which case you can only find a nearby repair shop to solve the problem; 2. The fuel pump has a problem, you can try tapping the fuel tank to start, if that doesn't work, you still need to find a mechanic; 3. Excessive carbon buildup in the throttle valve, you can try pressing the accelerator slightly while starting; 4. The engine is still in a cold state, especially for cars that have been parked for a long time, the operating parameters of the engine are completely different from the hot state of the previous day, and various sensors need to be readjusted. If you insert the key and start immediately, the operating parameters of the engine will be abnormal initial data, resulting in startup failure or multiple startup failures.
