Hello, the gray wire at the pump relay, carries voltage to the pump, should be hot with the engine cranking. Pink wire comes from fuse, should go hot when you turn on the key. The dark green wire with white tracer is voltage signal from the pcm to the coil side of relay, should be hot, with engine cranking.
Are there any codes? I just wanted to add, you can do some testing at the fuel pump relay in the power distribution center under the hood. The relay may have a wiring diagram on it. If one symbol looks like an open switch, one terminal is for the pink wire, the other gray. The symbol for the other side of relay, looks like a small coil, one of those terminals is for the dark green wire with white tracer. You can unplug the relay, have a helper crank it, use a testlite on the terminals for the pink and dark green with white tracer. Also make sure the relay is good.
