1996 Nissan 240sx with sr20det swap

Issue: Fuel pump is hard wired to the battery via relay and one day all of a sudden loss power. Things I tried
1. Checked fuses
2. Fuel pump works when directly powered via battery
3. Replaced relay with new one
4. Checked my connections and inspected the signal wire (b/y wire)
5. ECU checked by Martin (Rs Enthalpy) found to be in good condition. Tested on another car and works.

Pump does not prime/turn on when car is on position. Is there another relay or something else I can check? Car has been down for several days and would love to get her back on the road. Thanks in advance!
