One more test:

Unplug the DME harness from the DME and measure voltage at pin 4 on the DME harness. This pin MUST have 12vdc while cranking, does it go to 12vdc during cranking?

Pin 4 is tied directly to the ignition switch 'Start' it comes off the same line that feeds the starter.

If it does not then the fuel pump will never be energized.

Do this test and report result.
