1994 Toyota Camry no spark
NO spark or injector pulse. Battery voltage to coil and igniter. Have continuity from coil/dist and igniter and ecm. All grounds check OK. Do not seem to have pulse on negative side of coil when cranking. Replaced Dist, igniter and ecm with known good units. Still no spark or injector pulse. Are there any of the engine sensors, either shorted or bad that would cause this? Car is 4 cyl
