不是火花

Good morning, I have a Nissan Sentra 4 cyl, what he has is that the prinsy is not Avia spark in a spark plug (#4) and he came the bovine thinking that it was, and it did not remain the same, then the bad bovine came to him for the no.1 And if the spark plug was good but now it is worse because he does not have a spark in number "2" 3 " Checked nothing except for the bovines that Camvie. Someone who has experience in these imported汽车，谢谢你

汽车是2000年

它只是没有火花，或者对喷油器没有信号，您扫描了吗？？？

感谢您的回答，请注意，如果注射器中有一个迹象，那么4和Tamvien电池无法再扫描电池，乍一看会是什么？即使时间不足，Spark必须看到，但是我不知道这辆车，您对此有何看法？新思想。

In these cars there is a very common problem, and it is that the driver is damaged that controls the coils if there is an availability to buy another Ecu Aslo because as a rule in almost all vehicles if there is no spark Replace someone with knowledge and experience in repairing Ecus because work is very delicate and you have to know how to connect, identify the entrances and outputs of the IC and only 4 of the 6 inputs and outputs of the IC are used, the feeding is the same 5V but being the原始的最简单的IC给出了线圈故障，因为它没有诊断来向ECU指示线圈已连接。
