December 8, 201014 yr comment_338188 The unconnected dangling white wires by the ECU (computer) are common. They don't need to connect to anything,they are probably for diagnostics or quality assurance at the factory. I don't know for sure, I have not seen a solid explanation. But I have them and so do others. Don't worry about them.In the FSM, most or all of the wiring diagrams have the wires labeled with a letter. The colors that go with the letters are generally shown down at the lower right hand corner of the diagram. G = green, L = blue, WR = white with red stripe, etc. The connectors are also shown and they are color-coded also. So you can follow the wire color to the proper color connector shown in the diagram and you'll know where that wire should go. There are too many wires and connections to try and figure out your problem here. The circuit from your ignition switch to the fuel pump relay is not too complicated. I would start there and at the steering column and the combination switch and ignition switch wiring. The relay is right above the handle to open the hood. It has two connectors attached to it.

December 8, 201014 yr comment_338196 i saw that relay and i believe it the feul pump relayActually, it's two replays in one housing. The fuel pump relay and the fuel injection relay. You should have power from the ignition switch to that relay when you turn the key to On. Then the relay will allow power to go to the fuel pump when the AFM contact is closed. It might be worth your time to take the hose off of the front of the AFM, turn the key to On and open the AFM flap. If you have power to the relay, the fuel pump will turn on. If it does, then you'll know you have at least one correct fuel pump circuit.
