If a car suddenly stalls and fails to start, it may be due to fuel system or electrical circuit malfunctions. Fuel system malfunction in the car: When the car's fuel system is clogged or experiencing other issues, even if the battery is fully charged, starting the engine can be very difficult. However, this problem is not too serious and can usually be resolved by a professional mechanic with simple repairs. Car running out of fuel: Many careless drivers often forget to refuel their cars. If the car is out of fuel, it won't start even if the battery is charged. Electrical circuit malfunction: Check for short circuits or open circuits in the fuses and high-voltage coils of the electrical system. If these components are fine, then inspect the spark plugs. Electrical faults are generally caused by the central computer losing control functionality.

I've been repairing cars for over 20 years, and this kind of stalling and failure to start is all too common. Don't rush to start the engine yet, focus on checking these four areas: whether the battery terminals are oxidized or loose - high summer temperatures can easily cause poor contact; check if the fuel gauge light is on - last week I rescued a customer who simply forgot to refuel; inspect the ignition coil for cracks - a driver had this exact issue after rainy weather last time; also listen for a clicking sound when starting - if present, it means the starter motor is jammed. If you're completely stuck, check the fuse box, especially the 15-20A main circuit fuses. Use your phone to take a picture of the fuse layout diagram for reference.

What is the safest method for running battery cables into the cabin?

Route the cables from the firewall near the co-pilot's air filter to the engine bay, cover with heat shrink tubing and corrugated conduit, connect to a circuit breaker and fuse holder, then to the positive terminal. Inside the cabin, connect to a relay, control the relay switch, run the cables along the plastic housing of the co-pilot's footwell to the co-pilot's seat, and connect the wiring to the co-pilot's seat. Connect the positive and negative 16-gauge power cables to a two-in-one-out splitter, then connect the original power cables from the thick padding of the center armrest to the splitter to complete the wiring.

How to Handle Small Car Paint Scratches?

After noticing the scratched area on the car paint, observe whether it is located on the front bumper, rear bumper, or other parts of the vehicle. Generally, the front bumper, rear bumper, and fuel tank cover of a car are made of plastic, and the paint layer is relatively thin. If the scratch is minor and you don't want to go for professional repair, you can purchase a touch-up paint pen to handle it. However, if the scratch is on metallic or pearl paint, it is necessary to go to a 4S shop for a spray paint treatment. Typically, 4S shops perform spray painting on the entire panel.

What transmission does the Touran use?

The Touran is equipped with a 7-speed dual-clutch transmission. This model series uses a 1.4-liter turbocharged engine across all variants, and the dual-clutch transmission is particularly well-suited for pairing with small-displacement turbocharged engines. The dual-clutch transmission is currently a highly popular type of transmission, developed based on manual transmissions. Its structure is quite similar to that of a manual transmission, with the main difference being that the dual-clutch transmission has one additional clutch and an extra set of gear-shifting control mechanisms. In a dual-clutch transmission, one clutch controls the even-numbered gears, while the other clutch manages the odd-numbered gears. This type of transmission connects to the engine via clutch plates, resulting in relatively high transmission efficiency.

How to Unlock a Locked Engine?

Solutions for a locked engine: At this point, simply use the key to unlock it. Generally, aftermarket keys may not be recognized as effectively. If the original key also fails to unlock, disconnect the negative terminal of the battery for a period of time. Wait for the engine's protection data to clear, then reconnect the battery. It usually takes about 10 seconds of disconnection before reconnecting. Reasons for engine lock due to external factors: If the engine is locked due to a collision causing it to sink and lock, repairs are necessary, and the lock will be released once fixed. If the lock is due to the computer system detecting non-system certified components, it is recommended to visit a 4S shop or a qualified repair center for unlocking.
