Default fuel pump relay question

In my 00 2.5RS it had a wire going from the fuel pump relay to the ECU, (b134,16) Now that I have swaped in a 2004 ej20 ECU,it no longer needs this wire. I'll be hooking up the fuel pump controller black/yellow wire to the black/red power wire,but what to do with the relay control wire?....EDIT,after looking over the two wiring diagrams it looks like I could just ground this wire and then the relay should work, yes/no?

1998 outback


got a 98 outback... won't start when it has ran a while and you shut the engine off and try to restart it... it cranks but won't start up. I can't hear the fuel pump buzz when I turn the key on. I have changed the pump, but still does the same. Thinking it might be the fuel pump relay or the ecm. what is the most common problem? don't want to spend money on a ecm. seams to restat after it cools down. are relays a dealer part? how much?

1993 subaru


thats really strange, i have a 1993 impreza saloon wrx and i have the exact same problem your having. When my car was cooling down it would start up again then stop i dont think shes getting fuel to the engine. Now she doesnt even start at all. I think my fuel relay has blown or my pump has gone. any suggestions.
