What could cause a fuel pump to have no power besides the fuse or relay?

Question

2004 Saturn L300 V6. The fuel pump does not come on. The fuse is good. I have replaced the relay with a known working identical relay. When testing the 7 pin connector at the tank there is no power to the pump. Is there anything else that could stop the current from getting to the pump?

Answer 1

The fuel pump circuit is energized for 2 seconds when the key is first turned on. After that the power for the circuit comes through the oil pressure switch when there is oil pressure. Check engine control fuse-10 amp in the underhood fuse block. Check & see if the fuel pump relay clicks for 2 seconds ,when the key is first turned on. The engine control module supplies the ground to complete the fuel pump relay circuit.
