"I then checked voltage at the main pump power wire and it was good. So it looks like I need a new main fuel pump. I believe this also proves that my fuel pump relays are working correctly too".

No, the jumper at the 3-pin plug pointed to the failing Main pump*, but it completely bypassed the FI relays. So you'll have to wait till you have a working Main pump to see if the relays work.

Be thankful you have LH because the K-jet Main pump is about $200! Tapping the pump with voltage applied is worth a try.

* Had the Main pump been OK, the jumper might have quickly blown the 8 Amp fuse #12, quite possibly compounding or confusing your efforts. Fuse 12 is not meant to carry Fuel pump current — which normally comes from the 25 Amp blade fuse up near the battery and coil.
