Your problem can also be with the Bosch ECU, these are prone to failing and also control the fuel pump, they can however be rebuilt.

on the drivers side left rear frame next to bumper bracket there is a ground for the fuel pump make sure it is not cut or rusty . the 4.3 has a oil sending unit at back of intake it controls fuel pump . oil sensor tells the computer to give power to fuel pump.

The wire should not be hot until the relay is triggered. The relay does not get triggered until the ignition key is turned on. It will run for 3-5 seconds or until the system pressure it at max.
