SoCal - Thanks for the detailed steps, so far no good news. There is voltage at the coil. The voltage on the injector plug reads identical (battery voltage) on both terminals. I was able to adjust the reference sensor gap as well. Fuel pump is brand new and pretty quiet. With my hand on it I can feel it running when the engine cranks. If I disconnect the number one cylinder wire and attach it to a spare plug, the plug sparks once right when the key is turned on (before cranking). When the engine is cranked, still no spark. Based on what you say above, I've narrowed it down to the sensors or the DMS. Is it true that only the reference sensor need work for the engine to fire, or do both sensors have to work? Is it true that the DME relay is mainly for the fuel pump and not the ignition?
