no pulse to fuel injectors?

Have you verified one side of each injector connector is live with +12V constant, and the other side pulses to ground when you crank the engine? Probably the easiest way to check this is with a powered test light. I would check the pulses from the speed and reference sensors at the ECU connector.

Here’s what’s crazy, I had 12v at the injector harness, I had spark verified with a spark light, I used a rest light to double check 12 at the injector harness, I had tach pulse, and I had 900 ohms from each speed/ ref sensor, at the DME plug. yet still no fuel from the injectors.
it turns out it was the plug to the reference sensor had been bent in a weird way that the old cracked wiring was either shorting or not making contact during cranking. I bent the plug back and up and the car started right up. So I know I need to replace the connector, but what I don’t know is if I can just cut and solder and call it a day with the ground being shielded.
