Why won't the car start after going through a puddle?

If the car won't start after going through a puddle, it's likely due to water entering the engine. Here's an introduction to water-damaged vehicles: Definition of a water-damaged vehicle: A vehicle is considered water-damaged when water accumulation occurs and internal components are affected by the water. Water-damaged vehicles are classified into different flood levels. Classification of water damage levels: Level 1 - Water just reaches the vehicle's chassis; Level 2 - Water reaches halfway up the wheels; Level 3 - Water almost completely submerges the tires; Level 4 - Water reaches the engine hood; Level 5 - Water completely submerges the engine hood; Level 6 - Water submerges the roof of the vehicle.
