What to Do When a Vehicle Fails to Start After Water Immersion?

[LeAnna]

If a vehicle fails to start after water immersion, the owner should push the vehicle out of the deep water area. If capable of inspection and repair, the owner can remove the spark plugs manually, cut off the fuel supply system and ignition system, and then use the starter motor to operate the engine, allowing the internal water to drain out. Subsequently, check various fluids for signs of turbidity or foaming, and replace them promptly if necessary. Owners who cannot perform these checks themselves should contact a repair shop as soon as possible for corresponding maintenance and inspection. Before driving through water, observe the depth, direction, and speed of the water, and assess whether there are obstacles such as mud or quicksand beneath the surface. Wrap the distributor and high-voltage wires with plastic film or similar materials before water immersion. Pay attention to the route and speed of the vehicle ahead to gauge the water depth and determine if your vehicle can pass through safely.
