from the distributor, no spark for 2 wires. also no injection pulse to the injectors.
what could cause both of these problems at the same time?
has spark at 4 out of 6 at the cap. will start with carb cleaner in intake, then stops when carb cleaner runs out

A likely fault with the ECU. Check the spark plug wires and distributor cap.

what sends the signal, the distributor or crank sensor.
also does the ECU have an indicator light, red or green?

Crank sensor is within the distributor.

Sorry I do not have the information for the ECU LED indicators.
