After a long series of diagnostics on my 86.5 I have discovered that the probable cause for why I'm not getting any spark is that somewhere in my wiring harness there is a problem with getting juice to the distributer. I have no power to the M-REL, or between terminal +B and body ground. I got to the ECU with a voltmeter and started testing things as per the TSRM, but I've come to the point where all it tells me to do now is check the wiring harness. Has anybody else had this problem? And is there a way for me to determine which wires need replacing and where? or should I just look for a completely new wiring harness(where? all ebay has are turbo harnesses) If anyone can offer advice or point me in the direction of a thread that addresses this problem I would greatly appreciate it. I have a friend who is a toyota mechanic, but he says he isn't particularly skilled at electrical diagnosis, so if somebody can help us get past this roadblock hopefully I can get my car running!
