ECU code help - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So the check engine light on my 1990 240sx fastback came on recently. I pulled out my ECU and from what I can tell it's spitting out a 45. Here is my text interpretation of what I get. It flashes twice, Then three times, Then four, Then five. I'm assuming that's 45 which is supposed to be an injector leak (According to my uber ECU book) but I checked and none of the injectors are leaking. So I figured what the heck and pulled off the negative battery cable to reset it. When I reconnected the cable and started the car the check engine light was on. I checked the ECU once again and got the same codes. Any help on this would be very much appreciated.
