Hello, look for rpm signal. Without rpm signal, I don't believe the computer will ground the injector/s.
The purple wire with white tracer at the distributor, carries the rpm signal to the computer, with the engine cranking. There should be a pulse on that circuit. If you have a dmm that has a duty cycle-- dwell--tach setting, any of these settings will react to a pulse, also a digital logic probe.
