Z31 ECU Swap Questions/Issues/Codes/Feedback

[DuoWing]

I don't have any questions on wiring this up, mainly I just wanted to see if anyone can chime in that's done the swap. I'm trying to get my 280ZT running. Well it runs, but could be better. I'm trying to narrow down issues and I wanted to see if anyone has had this problem. I had the Z31 ECU swap all setup and running pretty much perfectly before I tore my turbo motor and harness out of my old 83' 280ZXT. Anyway I was always getting an error code for the fuel pump circuit. Code 22. I was wondering if this is just due to the different way we have it wired if you follow Afshin's guide? I was curious if anyone else has a Z31 ECU running with no issues and is getting this code. Also it's weird as I'm not seeing a code 21 for an Ignition problem, but on the later 87-89 ECU that lets you do the real time diagnostics I'm seeing two codes basically for the fuel pump, and one for the ignition. I don't always see the ignition, and I pretty much always see the fuel pump one, but the only time is right when the car starts up. I won't see it again while running. Either or them, or at least I've yet to see them again. So basically is there anyone out there with a Z31 ECU swap that has essentially a perfectly running car that sees these issues? I'm just hoping that my cold starting issue is more related to something other than my ECU/Wiring.

 

Any help/info that you guys can provide is as always, greatly appreciated.
