Coil negative connection to ECU is needed otherwise wouldn't run at all (tells the ECU when to fire the injectors). A couple of possibilities off the top of the head:
Are you using the full 280ZX ign system, particularly the coil (no ballast) ?? Do you have the injector dropping resistors in place ?? >Is anyone familiar with the EFI from a 280ZX? I've just fitted an L28E from >a 280ZX into a 1975 Datsun Laurel complete with the injection and I have a >problem. I've wired it up as it should be according to the Nissan diagram >and it started first time but won't rev over 1800 rpm! At that speed the >injectors cut out and it dies until the revs have dropped a bit then the cut >back in. > >I've checked all the connections and everything seems fine. The system was >running fine before the transplant. At first I thought it may be a faulty >AFM but I've tested it and the wiring harness and it's fine. I've even tried >a different AFM but there was no change. The fuel pressure is fine (I tested >the VW pump before fitting and it was good and I've fitted a new regulator) > >The only connection from the ignition to the ECU is the one from the >negative terminal on the coil to pin#1 on the ECU....could this be causing a >problem? --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ ---------------------------------------------------------------------
