POSSIBLE FUEL PUMP PROBLEM

I have a question about the wiring. On the right side it has a 6 prong plug.
The wires are black, black & white, black, green & brown, red & white, and orange. The green & brown wire will illuminate for a few seconds when the key is turned for going out. When you turn the key to crank it the wire will come back on. The pump will not run at anytime.
Also, can someone give me a breakdown of what each wire does.

Fuel pump power and ground, sender power, low fuel light sender and cross over pump.

It sounds like you have a failed pump. Did you check the actual pressure?

Thank you for your quick response. I have not checked the pressure yet. I will let you know what happens after I do. Thanks again.
