1. Identify the cause of the obstruction. To deal with the problem that the concrete transport mixer cannot start, the battery should be tested first. It needs to be clear whether the battery is low.

2、檢測啟動系統(tǒng)。檢測它的啟動系統(tǒng)中的電路。從根本的構成形式來看，啟動系統(tǒng)的電路一般來說包括：蓄電池、啟動電機以及毗連這些部件的電纜等。除此之外，焚燒開關、啟動機繼電器或電磁線圈，尚有車載防盜系統(tǒng)等，也同樣是啟動系統(tǒng)的重要構成部分。

2. Test the startup system. Check the circuit in its starting system. From the basic form of composition, the circuit of starting system generally includes: battery, starting motor and cables connecting these parts. In addition, incineration switch, starter relay or electromagnetic coil, as well as vehicle anti-theft system, are also important components of the starting system.

3、檢測焚燒正時皮帶呈現了打滑現象，是導致沒有電火花發(fā)生，也是它無法啟動的原因。

3. The detection of the incineration timing belt showed a slip phenomenon, which is the reason that there is no electric spark and it can not start.

4、檢測電火花質量。可以取下焚燒線圈，然后用一個電火花檢測器檢測電火花是否正常。

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

5、檢測燃油系統(tǒng)。它的燃油系統(tǒng)的診斷可以分為兩部分：燃油供給系統(tǒng)的診斷和噴油器電路系統(tǒng)的診斷。燃油供給系統(tǒng)可以通過丈量燃油的流量和壓力舉辦檢測。丈量燃油流量的好的方式，是在燃油供給管路中帶負載時檢測管路。

5. Test the fuel system. The diagnosis of its fuel system can be divided into two parts: diagnosis of fuel supply system and diagnosis of fuel injector circuit system. The fuel supply system can be tested by measuring the flow and pressure of fuel. A good way to measure fuel flow is to test the fuel supply line with load.

6、檢測防盜系統(tǒng)：它的防盜系統(tǒng)也會發(fā)生一些經常被忽略的燃油供給系統(tǒng)方面的妨礙。一些攪拌車制造商在防盜系統(tǒng)數據流中包羅了參數識別機能。在很多車型上，改換防盜系統(tǒng)的模塊而沒有對它舉辦正確的初始化處理懲罰。

6. Detection of anti-theft system: its anti-theft system will also occur some of the fuel supply system which is often ignored. Some blender manufacturers include parameter identification function in the data stream of anti-theft system. On many models, the anti-theft system module has been replaced without proper initialization.
