Gen1dak will become famous soon enough

Since you just changed PCM, the only thing between the coil and the PCM is the ASD. Now, the ASD also supplies power to the fuel system. I know you said you had good fuel pressure, but I'm thinking that even at 5 volts, a fuel pump could build up pressure to the limits of the fuel pressure regulator since the engine is not consuming any fuel. Of the three conditions I'd listed, the two you don't have lists the PCM, PCM circuit, or the 60-pin connector. Only the constantly low voltage lists PCM or ASD. Since the PCM energizes the ASD (either on or off, not variable voltage), well, that'd have me changing the ASD. Always possible it could be something else, but at this point I'm at a loss if it is. ASD's don't fail often, and can be tricky to diagnose, but that's where I am at this point.
