No Power To Fuel Pump Issue

I haven’t seen or read up on an issue like I’m having. At least nothing in what I’ve found yet. Previous owner did a hack job in wiring... been working on fixing all of it.

Car: 1995 S14 OBD1

I’m getting no power to the plug that connects to the fuel pump.

I was following a “no fuel” issue how to. Here’s the how to: http://driftbasic.com/troubleshootin...prelay-issues/
When I came to this step...
“Pin #2 is ground signal from ECU, it can be verified by checking for continuity between Pin #2 and a ground point while key is in the ON position (it will only work for couple seconds after turning the key)”

I get continuity when the key is in the OFF position. When I turn to the ON position, I get nothing. This is backwards from what it says it should be. Any ideas why? I’ve been stumped on this for the past few days.

All relays check out and work, fuses are good, everything else I’ve check seem to be in working order.
