Is it possible that four injectors are broken at the same time?

It is possible, but this rarely happens, and the probability of fuel injector damage is still very small. The common damage forms of a single injector are: 1, and the needle valve is blocked; 2. The needle valve is not tightly sealed; 3. The injector solenoid valve is faulty. According to the different control modes of injectors, it can be divided into: 1, sequential injection; 2. Group injection; 3, spraying at the same time; If the control mode is an electronic control system with simultaneous injection, if there is a problem with the electronic control unit, the four injectors will not work at the same time; In addition, if the ECU does not receive the speed signal, the fuel injector blade will not inject fuel; Therefore, it is suggested to overhaul the fuel injector control circuit and sensor. Hope to adopt, thank you!
