My fuel pump went bad so i replaced with a electronic one, there is no power coming into the fuel pump. If i wire it direct to the battery the pump does work, but pumps way too much gas. I have traced the wiring, making sure the ground is good, and the white wire that goes forward to the ignition switch and fuse box. Why do i have a black wire going from the fuse box along with the white wire from the fuel pump, it goes to the starter, is this a mistake on my part, isn't there suppose to be a brown wire there underneath the white wire that goes into the fuse box.  Thank you  Jim

You don't say what car you have but, regardless, there should never be a black wire to the fuse box. Commonly there is a white wire from the ignition switch to one fuse with another white from the same side of that fuse goint to the pump. The other side of that fuse has a bunch of green wires. The brown wire should feed the other fuse.
