Okay, fixed most of if! The two yellow wires in the diagram don't get enough power from the two yellow and red wires going to the ignition relay, only 4-5v. So I wired the FPR yellow wires to the "on" position on the ignition. That fixed it! But only if I ground the green Ecu wire on the fuel pump relay, and I get my 12v at the power wire heading to the pump!
That's the wrong way to do it. The ignition relay is there for a reason. You need to find the source of the voltage drop, not remove components and wire around them.
Any ideas why the Ecu isn't grounding the fuel pump relay?
Hard to say - probably missing a ground source or power source.
Could I just leave it grounded, since I have both power wires on in the "on" position on the FPR?
No. The pump will continue to run in an accident scenario and could cause a fire or fuel spill.
And that diagram from what I'm exsperincing is wrong... :/
I've stripped more harnesses than I can count and it's never been wrong that I've seen.
Don't know how you feel about safety but when I finally get to my ej swap on my 87 gl definitely going to add a low oil pres switch to the circuit like this:

Voltage from the ignition switch starter wire while cranking & ignition hot thru the Hobbs switch while running. If the engine stalls & OP goes below 4 psi the FP cuts off.
Completely uneccesary and a waste of valueable time and resources. The ECU already handles the fuel pump shutdown by cutting out the fuel pump relay when there is no ignition pulse (tach signal) present. The wiring, hardware, and software is already in place to support the "safety" you desire so adding additional components and wiring is just wasted effort.
