What would make power not let the fuel pump come on when you turn the key on. We changed the fuel pump, filter and fueses and it still want come on.

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?
