Check voltage and ground at fuel pump connector. If you have good voltage and ground at the fuel pump, and no fuel pump action, the fuel pump is faulty. Some of the national brand autostores used to loan out a fuel pressure gage.
Did you check the voltage at the fuse in diagram, is fuse ok? The pcm sends voltage to the coil side of relay. The ground for coil side of relay is constant. At initial prime, key on, no crank, The pcm sends voltage to coil side of relay for about two seconds for the initial prime, green wire with white tracer. The control side of relay and load side of relay have different voltage sources.
