Welcome to the forum, I'd check for voltage and ground at the pump connector, engine cranking. If you have good voltage and ground and no pump action, I suspect the pump. The gray wire is voltage for the pump, black is ground.
If no voltage, check fuse 16--20 amp, use a testlite on the fuse circuit, goes hot when you turn on the key.
