My sr swap is in my 92 s13 is about done and it won't start because the walbro fuel pump i installed isn't turning on. It's getting 10-11v after i cleaned the plug because it looked coroded and before i cleaned it i got 4v thru the plug.

Do walbro pumps need a full 12v before they will turn on? Do i need to hardwire it so that it recieves 12-13v?
