Hmmm GTV 24v 3.2 ltr fuel pump primary circuit problem

This is following on from my ECU problem. I have located a 2nd hand virgin ECU and the engine will not start for lack of fuel. The fuel pump relay in engine bay ( relay # 2 ) is receiving a constant 12 volts and is good, however, my information is that the fuel pump & pressure is controlled by the earthing ( grounding ) of this relay. The only way to get the engine to start is to put the earth wire for the relay to the car body. The fuel system only has one feed pipe with no fuel return and so I assume that something controls the earthing of the relay to control the pump & pressure. My engine light is on contantly and the code comimg up is P0230 " primary fuel pump circuit probelm " What is it ???. please HELP !
