I have a 1980 ZX Automatic with extractors and it is so rich that the engine will not run. I have had the ECU and the AFM tested and they were found to be ok. I have disconnected the cold start by blocking the fuel hose. The thermotimer and temp sensors have been replaced. All terminals have been cleaned and new clips fitted. The engine will start and run perfectly for a few starts then next start will just flood engine with fuel. I have to remove the sparkplugs and dry them out leaving them out for an hour or two then refit and try to start sometimes all ok the flooding again. I am thinking maybe just give up with this one and just fit carburetors.

 

Thank you to kickstart 80. The main trouble has been located and I now will locate the parts to repair the issues as described. It will require a new harness and distributor and maybe some other bits as well. I hope my problems with the 280ZX will help others in the future. Cheers
