Xiaobian's friend asked me for help on the way, saying that the car didn't catch fire. Automobile ignition failure should be a common automobile failure we will encounter. The following small series will introduce the causes and solutions of automobile ignition failure.
Cause I of car ignition failure
Generally, under normal conditions (no fault lamp, sufficient fuel), the reasons why the ignition cannot be started are:
1. The fuel filter is blocked
2. The filter screen of fuel pump is blocked
3. Check whether the spark plug has serious carbon deposition or ablation
4. The starting motor does not work
5. Oil supply of oil pump is not timely during cold start
6. Insufficient fresh air or fuel supply
terms of settlement:
When starting, step on the accelerator to increase the throttle opening, air intake and fuel injection, which makes it easier to start.
Cause of vehicle ignition failure - Case II
There are many other reasons why the car can't start, including open circuit, dead battery, water in the engine, etc., but in these cases, the fault light will sound, and you must go to the repair shop for inspection
There are two common situations:
The battery is dead. Pay attention to the service life of the battery. The general service life of the battery is about 80000 km in 2 years. Cars with battery power loss will give an alarm. What needs to be reminded is that the battery will not be charged at idle speed!
The problem with the fuel supply system is that the oil pump usually refuels. Pay attention not to go to informal service stations! Then clean the fuel injection nozzle regularly.
There are too many reasons. For example, the failure of the battery, the failure of the starter, the failure of the ignition switch, the dislocation of the timing, the failure of the ignition coil, the failure of the oil pump, the damage of the crankshaft position sensor and other electronic components will cause the car to fail to start normally. There is no way to avoid it. Only when there is a problem, go to the repair shop for inspection and maintenance
Check whether the battery is fully charged
Check whether oil is applied. Check whether there is a problem with the engine sensor with the diagnostic instrument. Generally, the problem with the crankshaft position sensor is that the car can not be started.
