Like a car, you have to hit it three or four times to get it. What happened to the new gasoline pump?

According to the car condition, temperature environment, etc., there are many reasons for poor starting. The main reason for poor startup is: 1. Starting voltage. Check whether the cold start voltage meets the use requirements. According to the standard, the starting voltage of the battery should not be lower than 10V during cold start, otherwise the speed signal during start-up can not be reached, and the requirements of the standard idle procedure during warm-up can not be met. Self-check detection is to see whether the tachometer pointer fluctuates around 200rpm when starting. This fault is also one of the reasons why this model is difficult to start when the voltage is too low. 2. Initial oil pressure: due to the long downtime, the oil pressure in the fuel system is too low or the pressure difference of the oil pressure regulating valve, it is impossible to establish a good standard oil pressure in an instant, which easily leads to insufficient oil injection during cold start, leading to poor start. 3. Start-up conditions and intake air quality, that is, at most, insufficient at start-up. The root cause of the fault is that the throttle is too dirty, which makes the throttle stuck, and the ventilation cross-sectional area of the throttle is reduced or zero.

The phenomenon of self-inspection is that the starter rotates very fast and has no resistance when starting through the tachometer and the starting sound. The quality of the mixture, that is, the fuel of the control unit did not completely enter the cylinder during cold start and enrichment, and was adsorbed on the carbon deposit produced by the valve. The phenomenon of self-inspection is that the engine tachometer rotates very fast after starting, which will be around 2000 rpm, and the general standard is around 1700 rpm. The solution to this problem is to clean the fuel and intake system, and then learn the idle air volume.
