1. First, you should go to a professional repair shop to use testing equipment to read the fault code, repair and replace it according to the fault code. 2. Second, if there is no spark, the engine cannot start. The root cause of the failure.
3. Check the startup system. For problems such as the engine being unable to start, the first step is to detect the circuit in the engine starting system.
From the most basic form of composition, the circuit of the starting system generally includes the following most basic parts: starting motor and cables connecting these components.
Of course, in addition, the starter relay or electromagnetic coil, as well as the vehicle anti-theft system, are also important parts of the starting system.
4. Check the quality of sparks. When the circuit of the starting system passes the test and proves that there is indeed no fault, you should focus on why the engine cannot run.
Generally speaking, the first thing to test is the engine's ignition system, which is also the simplest test.
In early ignition systems, you could easily remove it and use a spark detector to check whether the spark was normal.
When choosing a spark detector, an adjustable detector is preferable to a fixed design.
Because it allows you to adjust the detector to a smaller gap, so you can know whether there is no spark at all, or whether there is spark but very weak.
When the fault light comes on, it means there is something wrong with the engine. This is hard to guess. You need to use a computer to diagnose it to know the cause. It is recommended to go to a 4S shop or repair shop to use a computer to diagnose.
