I am working on a 1991 F250 that is not getting power to the fuel pumps. I have a 1989 truck that is mine and have the service manuals for it, but the wiring and colors all changed for the 1991 model since they switched to having the high pressure pumps in the tank. Does anyone have a 1991 factory service manual that can scan the page for me that has the schematic drawing for the "fuel control system" I need this so I can trace down where the problem is. It has all the wire colors labeled on the drawing. My 1989 manual has an excellent schematic drawing in the fuel system section, it is just not correct for this 1991 I am working on.
