Just put the ECU box on it and not able to get tach to work. Only thing left in my eyes is the distributor. Car started and drove it in the paint booth this am so should not be distributor but then it started just fine before I replaced coil, ECU ballast resistor and the voltage regulator. I have also added a ground from engine to body. Ground from battery to body. Everything else is stock. Just can not get things figured out.
