There are several reasons why a car may not supply fuel and fail to start: 1. Incorrect gear position: For automatic transmission cars, the gear must be in P (Park) or N (Neutral) to start. If it is in R (Reverse) or D (Drive), the car will not start. Some manual transmission cars may also fail to start if the clutch is not depressed. 2. Dead battery: This could be due to a drained battery caused by leaving the headlights on for an extended period or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing aftermarket components such as xenon headlights, high-power audio systems, or DVD players can also lead to electrical issues in the car. Checking for a dead battery is simple—just press the horn. 3. Spark plugs: Often, the first component to check is the spark plug, as it is a crucial part of the car's ignition system. The ignition system is key to whether the car's engine runs or not, so the proper functioning of the spark plug directly affects the vehicle's performance and efficiency. 4. Carbon buildup: Excessive carbon buildup in the engine can also prevent the car from starting. A common solution is to drive at high speeds regularly, which helps reduce carbon deposits.

What maintenance is required at 100,000 kilometers?

When a vehicle reaches 100,000 kilometers, a major maintenance service is required. The major maintenance includes the following: 1. Replacement of engine oil and the three filters. 2. Replacement of transmission fluid, brake fluid, power steering fluid, and coolant. Additionally, components such as spark plugs and belts should be inspected and replaced if necessary. The vehicle's tires and brake pads also need to be checked. 3. Finally, a four-wheel alignment should be performed to check if the chassis data has changed, with adjustments made if needed. Other tasks include a full vehicle inspection, which are routine items, and cleaning the engine's carbon deposits. Regular maintenance generally includes the following: 1. Routine maintenance, typically performed every 5,000 KM (or 7,500 KM for some models), primarily involves changing the engine oil and oil filter, and inspecting the fuel filter (many vehicles no longer have one) and air filter. If they are dirty, they should be replaced. Additionally, it is essential to check the brake discs and pads for replacement needs, top up brake fluid if necessary, and inspect tire conditions for safety. 2. Periodic maintenance, usually done every 3 years or 40,000 KM, includes cleaning the fuel injectors, throttle body, and the vehicle's intake system, in addition to routine maintenance. It also involves replacing transmission fluid, front and rear axle fluids, coolant, and brake fluid. Tire wear should be checked, with replacements made if necessary. 3. Major maintenance. This typically occurs after the vehicle has driven 100,000 KM and involves a comprehensive inspection of the vehicle and replacement of parts as needed. At this stage, the wiring (electrical circuits) and transmission components should be inspected.

What does the expiration date of motor vehicle inspection mean?

The expiration date of motor vehicle inspection refers to the validity period of the vehicle's annual inspection. If a motor vehicle's annual inspection is overdue, it means the inspection was not conducted by the due date, and the previous year's inspection validity has expired. Failure to conduct the inspection on time indicates that the vehicle has not undergone the required annual or biennial qualified inspection. For example, if the validity period is until October 2019, it means the motor vehicle inspection is valid until the end of October 2019, and the inspection should be completed on schedule. Vehicles without a valid inspection are not allowed to drive on public roads, and driving without inspection may result in penalties. The owner of the motor vehicle can apply for an inspection compliance mark at the vehicle registration office up to three months before the expiration of the inspection validity period. Before applying, the owner must resolve all traffic violations and accidents related to the vehicle. When applying, the owner must fill out an application form and submit the vehicle's registration certificate, compulsory traffic accident liability insurance certificate, vehicle and vessel tax payment or exemption certificate, and motor vehicle safety technical inspection compliance certificate.

Why Can't a Diesel Vehicle Accelerate or Pick Up Speed?

Diesel vehicle unable to accelerate or pick up speed may be caused by: clogged filters, blocked fuel injectors, high-pressure fuel pump pressure loss, or clogged air filters. Regardless of the cause, professional tools are required for repairs, so it is recommended that owners take their vehicle to a professional auto repair shop or 4S dealership for inspection and repair, rather than attempting to fix it themselves. Below are detailed explanations: Clogged Filters: If the diesel filter is too dirty or clogged, insufficient fuel supply can cause the vehicle to be unable to accelerate or pick up speed, necessitating replacement of the diesel filter. Blocked Fuel Injectors: Blocked fuel injectors lead to insufficient fuel intake, preventing the vehicle from accelerating or picking up speed. Cleaning or replacing the fuel injectors is required. High-Pressure Fuel Pump Pressure Loss: Pressure loss in the high-pressure fuel pump results in low fuel pressure, making it impossible to accelerate or pick up speed. Repair and calibration of the high-pressure fuel pump are necessary. Clogged Air Filters: If the air filter is too dirty or clogged, insufficient air intake leads to poor combustion, preventing the vehicle from accelerating or picking up speed. Replacement of the air filter is required.
