Each system of the automatic feeding and mixing truck is normal, but it can not be started. What is the reason? Next, I will teach you the key points of diagnosis.

1.确定阻塞的原因。为了处理这种全自动上料搅拌一体车无法引发此类障碍的诊断，应测试电池。需要弄清楚电池电量是否不足。

1. Determine the cause of the blockage. In order to deal with the diagnosis that this kind of obstacle can not be caused by the automatic feeding and mixing vehicle, the battery should be tested first. We need to find out if the battery is low.

2.检测启动系统。在启动系统中检测电路。在基本配置方面，用于启动系统的电路通常包括：电池，启动器电动机和连接这些组件的电缆。此外，焚烧开关，起动继电器或螺线管以及车载防盗系统也是启动系统的重要组成部分。

2. Test the start-up system. Detect the circuit in the starting system. In terms of basic configuration, the circuits used to start the system usually include: battery, starter motor and cables connecting these components. In addition, incineration switch, starting relay or solenoid and vehicle anti-theft system are also important parts of the starting system.

3.焚烧同步带的检测出现打滑现象，不会产生火花，这也是无法启动的原因。

3. The detection of the incineration synchronous belt has the phenomenon of slipping, and there will be no spark, which is also the reason why it can not be started.

4.检测火花的质量。可以取下焚化线圈，并可以使用电火花探测器检测火花是否正常。

4. Check the quality of spark. The incineration coil can be removed and the spark detector can be used to detect whether the spark is normal.

5.检测燃油系统。其燃油系统的诊断可分为两部分：燃油供给系统的诊断和喷射器回路的诊断。燃料供应系统可以通过测量燃料的流量和压力进行检测。测量燃油流量的一个好方法是在燃油供应管路中加载负载来测试管路。

5. Check the fuel system. The diagnosis of fuel system can be divided into two parts: diagnosis of fuel supply system and diagnosis of injector circuit. The fuel supply system can be detected by measuring the flow and pressure of the fuel. A good way to measure fuel flow is to test the line by loading the fuel supply line.

6.防盗系统的检测：其防盗系统也会发生一些经常被忽视的供油系统。一些全自动上料搅拌一体车制造商在防盗系统的数据流中包含参数标识。在许多型号上，防盗系统的模块未经适当的初始化处理就被更改。

6. Detection of anti-theft system: the anti-theft system will also have some oil supply system which is often ignored. Some manufacturers of fully automatic feeding and mixing vehicles include parameter identification in the data stream of anti-theft system. On many models, the anti-theft system module has been changed without proper initialization.

以上是全自动上料搅拌一体车无法启动诊断方法的问题，当然，其他未提及的方面也会对其产生影响，希望以上内容能为您提供参考。

The above is the problem that the fully automatic feeding and mixing vehicle can not start the diagnosis method. Of course, other aspects not mentioned will also affect it. I hope the above contents can provide reference for you.
