SR20 engine in Nissan V16 or Tsuru that does not start :(

Perrines I need urgent help to get this kxo off. What happens is that I bought an SR20 engine of a Nissan First 99 supposedly and mount it in the V16 and perfect and everything, but at the time of making the complete connection of the electronics I did not want Bencina does not send any signal. The ECU connector came with the immobilizer cable, but I don't know if it brought it or not and if the ECU was with any data before it was withdrawn as I do not have anything that is needed for ignition.

It would be very grateful if anyone knows about this engine and this year and if the ECU is blocked with the immobilizer, if there is any way of making a bridge to inhibit this signal if it is blocked

Friend, I believe that the problem is another because the immobilizers only act on a part of the vehicle or system not all the system, that is, they usually cut spark You know if it works or not, it is not a very good idea.

The engine is good with all its parts the only problem that it had is that the branch came cut that is the most common in an engine when they arrive from Japan. There are 2 cables that leave the ECU that have no idea what they are do not appear in the autodata or in manuals. I also have a black wire that comes out of the distributor that I have no idea where I will go (it has 6 pins this connector)

What engine was what you had previously? A SR20DE HIGH PORT O LOW PORT? The High Port brought the injectors above the admission multiple the lowport below and more hidden.

Computers and harnesses that control the coil injection engine and others are different for both engines as I understand for the Tsuru (B13) is OBDI and for the B14 and B15 it is already OBDII.
To run a Low Port engine on a B13 platform, both the engine of the engine and its wiring are necessary, otherwise you need the manuals of the B13 and B14 to know what cable makes and adapt the harness of the B13 so that it has the signals and voltages in need to run the engine and computer of the B14 or B15

luck and it is not for anything but it is a heavy work adapt an harness of one model from one model.

If it comes out of the distributor, it is most likely to be to command the spark and if it has as an album inside it is likely to control the injection pulse. Eye if the other cable is computer land will never leave you
