hello, if there is no primary voltage to coil, or the injectors with the engine cranking, check for voltage input to the asd relay, if you haven't already. Voltage for the switch side of relay is battery voltage, hot all the time. The voltage for the coil side of relay is ignition feed, goes hot with the key on. You can unplug relay and use a testlite.
