My 1991 F250 will not idle. changed plugs, fuel filter, rotor, c02, fuel control and coolant sensor. Still will not idle

If it is just idle that is the problem, check for a vacuum leak. A vacuum leak only effects idle, not acceleration.

You have a wiring problem somewhere. Probably a broken wire causing not enough voltage to get to the fuel pump. Maybe just a few strands of wire inside the insulation are still together. You are going to need a schematic to trace them down.
