Bunjiro Posted October 25, 2010 Share Posted October 25, 2010 I picked up a 75 280z from a friend for cheap. I was told it needed an ECU because all the injectors were grounded out. Turns out it was a bad AFM. Get the fuel issue all taken care of and now I have no spark. I have 12 volts going to the coil, but nothing coming from the coil. Replaced it with a new Accel coil and still nothing. I am about to put the car out into the highway so if anyone has some advice, please let me know.

NewZed Posted October 25, 2010 Share Posted October 25, 2010 Here is a link to a free downloadable Factory Service Manual. Wiring diagrams are usually shown for each component. Looks like the 75 files have some issues but they might help. Look in the Body Electrical (BE) section. http://www.xenons30.com/reference.html Is the tachometer in place and connected? The tach is part of the "spark" circuit. These cars won't run without it connected. Quote Link to comment Share on other sites More sharing options...
Bunjiro Posted October 26, 2010 Author Share Posted October 26, 2010 Not to sure on the tach issue. It was a guys daily before it was mine so I would assume it was working. Quote Link to comment Share on other sites More sharing options...
