Default 1995 sc400 fuel pump wont turn on

Hello, before I start I just want to say i am not new to these cars and don't want any newbie answers thank you.. onto the problem Fuel Pump will not turn on.
Fuel pump replaced
EFI relay replaced
All fuses checked
Ran power directly to pump still wouldn't turn on
12V mod done
when I turn the key I don't hear the pump kick on at all
will crank but not getting fuel
This car has been 1J swapped its not the computer it was having the issues before the swap (dont ask I got the car like this)
Previous owner had tapped into a ignition switch wire to get the car to start'
Fairly stumped but only been at it a day any input would be appreciated, I may replace the fuse panel and go from their
All lights come on and all electronics work
Thanks

Either the 12v direct and/or ground is bad or the fuel pump is bad.

Somebody tapped into EFI relay underneath the board I grounded out one side and it fixed it (for now)
