97 F-350 7.3PSD Died while I was driving it just a day after I replaced the fuel pump. I got to a parking lot and tried to start it. There was no wait to start light and it didn't start just turned over.I got out and opened the hood to find the #9 20a maxi fuse was blown. I tried replacing it. It just blows when you turn on the ignition. I mistakenly thought the #9 fuse was for the fuel bowl heater so I unhooked that and it didn't change anything. I greatly appreciate any help.
