I already know your plug has two wires who said it didn't. One of those two wires is going to your relay I may have accidentally wrote which wires instead of wire when I said you can tell which color wire is going to your relay(which will have 3 other wires also going to it) if so my bad. This might sound like a dumb question but you did already check your fuse first right, if that is blown you will not get power to either your control circuit side(coil) or power circuit side(contacts) of the relay?
Relay coil = @@@
Relay Contacts = -\ -
12V+ in Run or Start --~~~(fuse)-------------- @@@ ------- ECM ground pulse (control circuit)
12V+ in Run or Start---~~~(same fuse)---------- -\ --------- Fuel Pump ------Ground (power circuit)
Hope that helps that is how it should be.
