Isuzu 3.0 motor failure

I think it is smoke, it also smells like Gasoil Mal Kemado, the Board is not, because the smoke is already kit

Hello everyone, reading the post, I lean to what Ismael says, in the sense that the control switchboard detects a malfunction in one of the main control rates, for me to carry out a diagnostic sertero it would be convenient to clarify what the code is the code, P0216 or P0261? The P0xxx codes are general to all OBD systems, however it can also be P1216 Isuzu Fuel Solenoid Response Time Too Short, or the fuel control solenoid in the pump is detected as a short -lived time of spare of short, the P1xxx codes are specific to each manufacturer, they do not mean the same in all brands and models, it is a possibility in the doubt of the doubt of the code that sends It would be recommended to clarify this, for my fundamental for the correct diagnosis, finally a blank packaging failure although it is positive, the symptoms do not indicate it and also having codes deployed by the control switch Tirones, and smoke (fuel in the wrong time in the engine), this is typical of solenoid fault, final Electronic control component, it is not always reflected in a test bench (such as the hydraulic tests of a cylinder head or block), although it is the correct way to diagnose, my experience tells me that it is only one more test within many, the conditions are not equal to the operation of the pump in the engine, of an intermittent failure, in addition the person indicates that manually guarantees the pump improves ... that is the failure of the fence control is clear. be
determined that it produces it .

Hello everyone, here I leave the Isuzu motor manual, emphasizing that it was shared by Mr. Ismael53, it is very good to post it since there is a lot of info for which this topic interests you.

greetings to all.

I, from what I have seen, the problem is in a fuel deficiency at the entrance, in a
nut Frio starts well, because there may be empty in the transfer pump, this emptiness, the bomb body is slowed down slowly, when it stops it ...

This condition of "Injecting little and wrong", is not fulfilled in cold, because the pump is "barley" and acting in electric advance.
It is when heating the problem: the ECU delays the advance, and the volume of gasoleum A have decreased inside the pump (the filling is slower by the obstruction) also reducing the amount to be injected.In this moment, the ECU tries to compensate "advancing" the point, which is not possible due to the lack of gasoline (hydraulic operation). This is what I think is happening. From there it is corrected part of the problem, if we move "by hand" the bomb, because this, in those conditions it cannot do so.
