losing fuel pressure on 1995 Dodge Ram Van 1500

i installed new fuel pump complete with fuel pressure regulator. in morning you turn ignition on and let it sit for about 30 seconds to a minute until fuel relay starts clicking . Once clicking stops the truck is good for the whole day. what makes that fuel relay click loud???

The clicking is from the magnetic coil pulling the contacts together. Try another relay.
