Adaptronic + aromotive fuel pump wireing

In need of some guidance, I blew a main engine fuse last week due to a short in the alternator. iv have fixed all shorts.
But when I blew the fuse my fuel pump stopped working. The ground and power wire from pump relay was wired directly to the ecu.

now the pump only works if I use a chassis ground to the fuel pump relay where the ecu ground use to be.

but it seems like the fuel pump is always working at 14 v or what ever the car is putting out. isn't it supposed to raise with rpm from 5-14 v? so the pump is not always pumping Max pressure.

my car is running extremely rich now at 10.1afr at idle! and I really think it has something to do with this. Could someone just tell me how this pump is supposed to be wired with the adaptronic ecu. I have pinouts but it doesn't tell me anything about what ground to use. The original ground from relay was wired to the (1W- AUX output six) which drives the lights on the dash.. and power is still wired to (3d- AUX Output 5)
any advice is greatly appreciated

It's like any other automotive relay.
Your fuel pump will always be seeing the same voltage of the car if it was wired directly/correctly in below link.
