I wanna start by saying thanks to all who have posted about these fuel system electrical issues. I have read many threads in this forum. They have gotten me to where I stand with my truck today. My issue seems to be typical to these trucks. I turn my key on. No prime at the Fuel pump. Unplug the fuel pump, check voltage, meter shows around 4.5 volts. Same 4.5 volt reading at inertia switch. Same 4.5 reading at fuel pump relay on the red wire. 12v at the yellow wires. Same 4.5 reading at the EEC relay red wire. 12v at the yellow wire. So where do I go from here? Any more help is greatly appreciated!!
