Hi, engine cranking, do you visually check for spark at the plugs? If you have spark everywhere, use a gage and check fuel pressure, engine cranking. Around here, some of the national brand autostores used to loan out a fuel pressure gage. My hearing is no good, I can't hear initial prime, or hear the pump, engine cranking, so I just use a gage.

Just wanted to add, there is an oil pressure switch in the fuel pump circuit, once you crank it enough to bring up oil pressure and the switch closes, the pump will run, even without the relay. Initial prime is only through the relay.
