Posted September 23, 20159 yr Motor quit while idling, cranks over but won't start, no power to fuel transfer pump and injector pump, code displayed [ no bus] on onboard system check. Help.
September 23, 20159 yr If you fill out your signature (year of truck, options, add ons, mods, etc) it will be very helpful to those who are "in the know"

September 23, 20159 yr I would start with the relay in the big fuse panel under the hood. Find the one for the fuel system and swap it out with another one see if that's it.
September 23, 20159 yr Do you know what your fuel pressure is pre-vp44? I would also hot wire the vp44 http://www.bluechipdiesel.com/vp44_diagnostics.html If you are seeing "No-Bus" then i would also VERIFY all fuses. Clean all leads to the battery.
September 24, 20159 yr Author Ok, got it working now, disconnected all the harness plugs and plug ins found nothing obvious but everything working now, thanx
