    Drove my 2007 4.6 to work yesterday, normal as always. Lunchtime, spins over but won’t start. Fortunately, I work for a school bus company and have two former Ford mechanics on staff. Long story short, checked fuses, no sound from fuel pump bingo, found the “problem”.
    Installed new pump and filter, still no starting. Put power to the old pump....dead. Set up the scanner and low and behold, bad fuel pump driver module. Attaching picture of the old module. Two holes corroded in the base. Don’t know how took who out, but all is well. I hope
    that this helps someone else solve a problem.

    ^ Wow! Is that corrosion caused by road chemicals used in Minnesota? Nasty stuff.

    I just saw a video on this and the new replacement part has a setup that keeps the mod. off the mounting point with special bolts that come with the part . This video was Ford Tech Makuloco fuel pump driver module
