Some friends often encounter the situation that the car won't catch fire and the key won't turn. At this time, it should be noted that if the steering wheel does not turn backward when parking, and it is at a slightly larger angle (for example, more than 30 degrees), the steering wheel will automatically lock, which is also an anti-theft measure. At this point, the key may not turn, resulting in ignition failure. First aid: Turn the key while hitting the steering wheel hard, and the steering wheel lock will usually be unlocked soon.
2. The battery is dead
Battery, also called storage battery, is a kind of battery. Turning on the headlights for a long time will lead to power failure, or the battery life will expire, or xenon headlights, high-power stereo, DVD, etc. will be installed. It is also the cause of vehicle circuit failure. The method of checking whether the vehicle is stalled is simple. Just honk. The old driver suggested replacing the battery in time in about 2 years. First aid method: call the service station for rescue, or find a car to check it, or catch fire temporarily, and then you must go to the service station to charge the battery.
3. The fuel filter is blocked?
Different degrees of blockage of fuel filter will also lead to insufficient oil supply and poor oil return, which will lead to too high pressure in the fuel system and too rich mixture. In this case, the car will not catch fire, or the car will shrug when driving. First aid method: Measure the pressure of fuel supply system and gasoline pump, and then change the throttle opening. The reading displayed by the fuel pressure gauge should change with the throttle opening, that is, the pressure value will increase with the throttle opening.
4. The gear is not adjusted?
When the automatic transmission is started, the gear position must be in P gear or N gear. If it is placed in R or D gear, it will not catch fire, which will bring certain safety hazards. If you are not in the P position when parking, you will ignore this problem when you get on the bus again. At present, general vehicles will be reminded on the display screen of the central control instrument, and some will be reminded with a buzzer, so the probability of this happening is very small. First aid method: put the gear in P or N gear.
5. The car ran out of gas.
The car ran out of gas, so it naturally failed to catch fire. When you find that the car won't catch fire, you should check the fuel gauge at the first time to confirm whether there is oil. Don't wait until the tank bottoms out before refueling, which will also affect the life of the engine. First aid: in this case, of course, hurry to refuel the car!
