The previous owner of my 91 4cyl to 5.0 swap wired the fuel pump in to run all the time. Anyone know how I could undo this and wire it up right? Im not good at electric work by any means, but aint afraid to try.

 

At the very least, these may be good starting points to see if it's hooked up correctly or to get hooked up correctly:
