    EFI fuse kept blowing (175,000 miles). Disconnected all systems as recommended. No change. Checked wire harness, especially in areas where touching metal. Wasn't obvious but found that the harness had worn through underneath middle of truck on driver's side. Harness rubbing against side of frame rail. Resistor wire corroded and broken; white/black wire casing worn off. Spliced in new wire and EFI problem corrected.

    P.S. In checking electrical system, found the underside of the starter cable covering had worn through from rubbing against frame (not obvious and starter was still working...for the moment).
