Welcome to the forum, yeah, check primary voltage to coil and injectors, engine cranking, dark green wire with orange tracer, should be hot. That voltage comes from the asd relay, that doesn't mean the relay is faulty, check the relay circuits for voltage and ground. The pcm grounds the relay, a common reason for no ground, the computer thinks there is a problem with the cam or crank signal circuit.
