I just replaced rear bumper, pass. Tail light assy. And now the truck turns over but will not start. I cannot hear the fuel pump engage. I have checked all fuses. I have checked the Auto Shutdown Relay. I have spark. I checked the 3 red wires potential corrosion issue that sometimes occurs in the harness "splice"
When replacing the bumper I had to remove a pigtail assy. For pulling a trailer. It was welded to the frame. Potential ground?
