Answer
Hi Tim,
If you have power on the dark green/orange while cranking then the rotational sensors are at least putting out signals that satisfy the PCM. No spark might then be attributed to a failer coil secondary (winding should read 12,000 to 18,000 ohms) or failed rotor or a cracked distributor cap. So see if the rotor is patent between the spring button and the tip of the rotor, and inspect tha cap for cracks. Remeasure the winding resistance and if at only 7,000 ohms then that would certainly cause a very weak spark or no spark.
