Astra Guayin 2002 Automatic Injectors Failure

Hello everyone:

I have the problem my astra where problem is that I have current and pressure on the gasoline injectors but they do not inject or do not open, someone can help me, attentive to their kind help,

already pay a lot in mechanics and they cannot hold it. greetings

hello. I imagine that several hands have already tried to find the problem you have in your truck, and I hope we can give some favorable result for this route. For this, it is important that you help us with more information, mainly the technical data of the vehicle and as the fault was presented. But not to answer the ask with another question, what I can leave by saying is that the injectors are electrovalvulas whose coil has a resistive value that goes from the order of the 14 to 16 homs being within these parameters we can say that the electrically the injectors are good. To verify the food signal towards the injectors when opening the ignition key contact in the injector connector (deck) there must be a presence of 12 volt with respect to mass.
If the aforementioned is mentioned above, the fault can be a sensor known as the Cñañal position sensor, who is responsible for informing the ECU position of the piston inside the engine and producing the injection.
Inspect this and tell us the result.
luck...........

I see it a little more complicated my friend, although the calculator is in charge of determining the time that the injector is open, I first check the injectors, but do not believe that they are the problem, that I put a computer because it smells like it is a reistence or the double relay.
