Hi all. I am going round in circles trying to understand how the ECU works.
To start with, I had a problem with one of my cylinders just not firing at all. After checking spark, leads, distributor, I finally found that the plug of the petrol injector had 12 volts on the one side and 5volts on the other side when unplugged. Also making up a jerry noid light, there was definitely no switching on or of the light when I cranked the engine over. Conclusion. ECU stuffed.
Bought a brand new one for £85.00 and thought that would be the problem solved. I checked the voltage on the injector plug and that is now fine. The car started and I could hear everything was fine, but after a couple of seconds it then cut out and does this all the time.
Now I am presuming it has something to do with an immobiliser. What else do I have to do with this ECU to get it to work? Do I have to take it to Nissan or an Auto electrical shop to have it programmed, or what? What is the simplest way. When I bought it, they did say it was uncoded, if that helps. Also it is an identical part no to the one I am replacing.
I have looked through the forum and everybody talks about Nats and rings. I have a 1995 Kll 1.3 with nothing on the keys. They all look plain black to me and no auto locking. It's all mechanical. I lean in the front door and open the rest from there.
Anybody with an answer would be much appreciated.
