88 k75c: no power to fuel pump relay

I posted this in the K-Bike forum but I guess this is a more suitable place for it.

The bike has been sitting for 3+ years and has about 29k on it. I have been trying to trace my problem for lack of power to the fuel pump. So far, I have traced in back to one of socketsn for the fuel pump relay (FPR) not getting ignition power.

If I am reading the wiring diagram correctly, there should be two ignition power sources coming from the ignition control unit (ICU) to the FPR socket. One of the wires from the ICU is not getting power to the FPR. Any ideas as to why the ICU is sending power to only one and not the other?

BTW, if I touch my light tester to the back of the ICU plug, the fuel pump relay will click and the light tester will shine but very dim.

Help?
