Nathanhill1402 Posted August 29, 2014 Author Share Posted August 29, 2014 swapped it out for another z32 i have, no luck but the 12v ground wire in the plug isnt connected to anything Link to comment https://www.sau.com.au/forums/topic/447387-dear-jesus-help-me-before-i-burn-it-r34-issue/#findComment-7377055 Share on other sites More sharing options...
Chris32 Posted August 29, 2014 Share Posted August 29, 2014 Obvious question, if the heads been rebuilt and cams have come out etc i'd be checking that the cam timing (in terms of their relation to the crank and the other cam) is correct. Sounds like the timing is out If the AFM was dead it still should idle Link to comment https://www.sau.com.au/forums/topic/447387-dear-jesus-help-me-before-i-burn-it-r34-issue/#findComment-7377058 Share on other sites More sharing options...
75coupe Posted August 29, 2014 Share Posted August 29, 2014 Water temp sensor?? Link to comment https://www.sau.com.au/forums/topic/447387-dear-jesus-help-me-before-i-burn-it-r34-issue/#findComment-7377070 Share on other sites More sharing options...
nicksamaniac Posted August 29, 2014 Share Posted August 29, 2014 Somebody correct me if im wrong? But if temp sensor (ecu temp sensor) is open circuit, wont it just assume a standard running temp and it wont add cold start enrichment or cold start timing? I had chronic cold start issues on a rb30et I used to own, would crank for 40+ sec before stumbling into life followed by 1/2hr of very poor running. it was the engine ecu temp sensor, and it didnt run right.

KiwiRS4T Posted August 30, 2014 Share Posted August 30, 2014 To make sure take the lead off the water temp sensor (the one with two terminals) - ecu should provide a default cold start map (at least stock one does - don't know about pfc).
