I bought a '98 Altima 5 spd. off of a friend who ran it into the ground pretty much. The car is only running on 3 cylinders and I have it deduced to the ECU being the problem. The #3 cylinder's fuel injector isn't spraying, so I went and bought a replacement injector to find it doing the same thing. So then I checked the voltage and found no current going through the injector plug. So I checked the wire harness from where it goes from the injector plug to the ECU to see if the wire was shorted or broken by running current through it and it flows electricity. I also checked the other wire that goes to the injector plug (ground wire?) and it flows electricity. So, I'm pretty sure the ECU isn't sending current to the injector. So, I've been checking ebay for replacement ECU's and have found some, but the sellers said I need to have the exact part numbers. Is this true? Or can I just purchase an ECU that came from another 5 speed 2.4 '98/'99 car?
