i just got done swapping out my ga16de for a sr20de in my 93 sentra xe.
i have swapped everything from the same car a 92 ser.i have completely rewired the car with the ser wiring and still the fuel pump does not come on.everything is working but the fuel pump.it worked fine before the swap.i have tested the wiring and only one has power with the key on.anybody have an idea what is wrong?

Fuel lines are prolly backwards. If thats not it check the black wire with yellow tracer for 12 volts. Its the 4th one from the left on the bottom row on the ECU. If you have 12 volts there, then check it at the fuse box, if its there, check it at the relay, if its there, check it at the pump, if its there, your pump is junk.

I hope makes sense.

well i tested the wiring at the pump and the center wire on the 3 wire connector is the only one that has power.should any of the other wires have power, there are 4 other wires?

Only two actual wires go to the pump I think. One should be 12 volts with the key on and the other is ground. You should be able to hear the pump kick on if you are sitting in the back of the car.
