no start - fuel pump will not run unless hotwired, injectors dont buzz either, cranks

1987 325is from the top: just got finished rebuilding engine. ~no power to fuel pump or injectors. when hotwired, the fuel pump pumps well. ~plenty of spark. ~fuses are fine. ~relays: when fuel is jumpered still no pumping. ~buddy seems to think ground problem. where to start looking for that? other notes: A/C system taken off running open headers just for the first crank (i.e. no o2 sensor)

Check to be sure that the main relay is one with five pins.
