Note the diagram, hopefully it is correct. Did you check fuse? The fuse circuit goes hot with on, you can use a test light to check for voltage at the fuse. The gray wire at fuel injector should be hot engine cranking, is it? Again you can use a test light. Engine cranking do you have proper fuel pressure? As you can see, it appears both the fuel injectors and fuel pump get voltage through the fuel relay. Any applicable trouble codes? For the fuel injectors in diagram, top wire is voltage, bottom wire is ground pulse.
