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

    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.

    I have A ford f-150 truck, won’t start, fuel pumps only getting 6 volts instead of the 12 volts needed, just installed new fuel relay. Whats the problem?
