VW ARNES failure

Hello friends, I have a problem with the VW 2000 harnes it seems to me that it is a short one I put the switch in IGN. The coil begins to download the injectors are activated-
Connect Test lamp to the reference signal of the harness of the coil and flickering as if it were extended this is the one that causes the coil to be activated and discharged.
What is causing this signal?

Those questions are difficult to answer without looking, first that is all connected correctly and after that, check the land, the vehicle does not start, right? Czech if it is missing spark or fuel, and Czech a state of fuses if there is a short short film must be as melts, look where it is the fuse that Sircuito and check only that circuit.

Thank you very much in fact the problem is that you open the switch and the coil begins to download the injectors work at the same time and this is only with the open switch I will continue looking for the problem is that I do not have the harmony of the harness and I do not know what are the feeds of the computer to check with another and I do not want to risk connecting it and burning the one that is fine anyway.

Do not put another computer your key is coded and you will block the computer that installs.
