NO POWER TO FUEL PUMP

2003 Mitsubishi Eclipse

Electrical problem
2003 Mitsubishi Eclipse 4 cyl Two Wheel Drive Manual

The engine was fine before the fuel pump locked up. After I removed the fuel pump, I tested the old pump to make sure that it was the problem. I checked it by connecting it to 12 volts and the pump would not operate-all it would do was click. Now-the new pump will not (run)operate. I tested the new fuel pump to make sure that it was good by applying it directly to 12 volts and it does run. But, when the pump is connected to the wiring harness, it does not work. I checked for power at the fuel pump connections-no voltage whatsoever. Checked all fuses in the engine compartment-they're ok. Checked all fuses in the passenger compartment-they're ok. I started checking the relays-but I was unable to identify the fuel pump relay nor the ASD relay. No wiring schematic is available-so I need help please!
