You might have a wire wrong - or maybe the wire size isn't large enough to carry sufficient voltage to run the pump. You should have ignition voltage through one wire to activate the relay, and a second (larger) wire coming from the battery to one side of the relay throw contacts, with another heavy wire from the other side of the relay throw to the fuel pump. You'll get better voltage from the alternator connection, but battery voltage should be fine.
I haven't looked hard at these 2 articles, but take a minute to see if you've covered all the basics:
Relay Wiring
Stealth Fuel Pump Wiring
