After re-reading this, I think. The next logical step would be to pull up the fuel rails one at a time and inspect/measure the injector flow (into bags or jars) to figure out what's really going through the injectors (if anything).
Brown gas? Hmm... I wonder if the injectors are simply totally clogged and the overall (low?) pressure from a previously seized pump (bound to eventually leak now) isn't enough to push the varnish through the injectors. Maybe the cold start injector is providing an initial squirt, but once that dries up, there's no fuel.
That's my hypothesis based on what I'm reading.
If you have the means to test the fuel pressure, that would provide another data point, but not necessarily tell you the quantity if fuel from the injectors.
My dream car is a classic sporty five speed (stick+overdrive) convertible that seats five. If, you want 70's-80's Mercedes tuner wheels, let me know.
