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.
