Default Fuel Pump wont prime

Good Day. My 2000 CBR 929 was stolen last year but was recovered shortly after. The lowlives cut the wires to the ignition switch and the right hand controls. What I have done so far. I replaced the ignition switch, and soldered and wrapped the cut wires, replaced the main starter relay fuse, replaced the tip sensor. Im getting frustrated at this point, When I turn the ignition on the display lights up but has a red mil light on at all times, I have tested the engine stop relay and it clicks when turning the kill switch on, there is no power going to the 3p connector for the fuel pump on the outside terminals, there is power on the fuel pump connector on the center prong but I don't hear the pump prime like it used to. there is power at the fuel relay when the key is on only. it will start and run if I spray starting fluid down the air intake so It is getting spark... Im kindof out of things to try... any new ideas would be awesome...

A few other things that I wasn't sure about. When I switch the kill switch from on to off the red mil light goes off for a second. Also, when I angle the tip sensor out of range the red mil light goes off for about 3 seconds.

Thanks in advance for your help and my apologies for the wall of text...

Make sure you're getting 9v on the pink wire that comes out of the ignition switch.

Also, check your grounds and the rest of the fuses. (including the FI fuse not in the box)

I think that is my problem... The only replacement ignition switch I could find was on ebay from China. When I hook it up, I have 0 volts from the originally pink wire (now the green wire)... On the old ignition switch there is a diode and the new one does not have that...

Voltage from new switch (original color):

Green (Pink) = 0 Volts
Black/White (Blue/Yellow) = 0 Volts
Red (Red/Black) = 12+ Volts
Black (Red) = 12+ Volts

Where can I get a factory replacement?

Thanks!

Thank You Demon! It turns out that the switch I bought was garbage. I swapped the tumblers out and used the old case with the new tumblers and works perfect. Sucks when you buy something and it doesn't work...

But thanks again for pointing me in the right direction...
