ECM wiring harness not directly connected to fuel pump. I bet it's your fuel pump relay that's going out, not the fuel pump - test the relay and check the relay connector for bad wires/connections.

yes on a 91 tni it is directly connected to the ecm. there is a prime wire and the main battery power wire is shared. it is orange.
