So then, how dose the pump engerize from a cold start? Will A engerize while cranking, untill the Alt starts charging? If the Alt fails to charge, will the pump cut out?

Ok. Im starting to understand how this works. Found the two relays. I see how they are connected. Now, it seems that im not getting power to relay A. So im trying to understand the chain of events that trigger the fuel pump.

Looking fot the pin out that feeds power to the fuel pump from the realy so I can see if power is going in and comming out if realt to the fuel pump. Am I looking for a green wire going in and a green going out or what pin on the connector feeds out to the pump.

Ok, I've found the relays.... now dose someone have a wiring diagram that shows what pin dose what?

Sorry for the delay on the sig update. Was having lots of issues logging. But here are the details none the less. It is a 1973 with 4 speed and AC. Has domed Carbs, not the flat tops.

Ah. Oil pressure switchn got it. I hear a click under the dash when key is set to run. Will check at oil pressure switch and then check for power again. Yes will be changing fuel filter as well. Had engine running from gas can and electric pump up front just for temp to see if engine was good. So far, everything is checking out. New clutch master and slave,and hose, new brake master everything bled. Just need to take around block to see how things feel, then wheea will come off to do full brakes

Working to get a car back on the road after a 20 year nap. Tank has been cleaned and reinstalled. Working to replace the electric fuel pump. However, power dose not seem to be making it back to the fuel pump. A kill switch was placed under the dash and that seems to work, power goes in and comes out of the switch and to the harness connector in the console under the radio, but no power is making it to the connector at the fuel pump. There are two wires at the pump with bullet connectors, one is ground (black wire) and I has been tested for continuity, the other will not read. I figure that there is a break some where between the console and the back of the car. How dose this harness route to the back of the car? I see it go up in the RH quarter panel, but what do I need to remove to trace these wires? Any help greatly appreciated.
