What year is your car, Scott? 90?
There are subtle differences in the ECU from 90 to 91. Typically, 91-94 are basically the same. Have you tried using your ECU in his car? The only obvious thing regarding the fuel pump that I can think of would be to verify whether the pump is actually receiving power. Grab your circuit light and verify.
I'm not sure, and can't seem to find further info on vfaq or 1000q ... but seeing as the 1.8L never came with a turbo option, maybe the ECU is sending a signal the fuel pump simply doesn't recognize. Or the ECU can't properly communicate with the 1.8L's fuel pump. I have no supporting info for this, but I know that if I were to throw in a 92 TSi engine into a body of a car that had a 1.8L SOHC engine, I wouldn't use the MAS, fuel pump or ecu. The ECU is blindingly obvious, but wouldn't the MAS and fuel pump go with this? Hell, under moderate mods, normal TSi's rewire their fp anyways.
Good luck.
