I'd use a gage and check fuel pressure, engine cranking. Also, unplug the fuel pump relay, use a digital multimeter where the relay plugs in, two circuits should be hot, engine cranking. Are they? The fuel pump fuse goes hot with the key on, check for voltage. A missing rpm signal could cause a problem, that would cause other issues, like no injector pulse. Could be wiring circuit problem somewhere. Can you check for codes?
