Your 1998 F150 has 3 relays for your power door locks : an all unlock relay / a driver unlock relay / and an ALL LOCK RELAY I'm guessing that the ALL LOCK RELAY has failed I'm sorry but I haven't found the location of the power lock/unlock relays on your F150 yet ( does anyone know the location of the power door lock / unlock relays on a 1998 F150 ? )

Ignition relay is probably shot. It is in the power distribution block in the motor comprtment.
it may not be you ignition relay, but your alternator.
It might be due to a dead battery or to a poor cable connection to the battery.
I know on my 1992 F150 it is under the hood behind the washer fluid reservoir in the black plastic power supply box with large fuses,relays and diodes.If you have duel tanks then their is one relay for each fuel pump.Hope this helps.

Under the hood on the drivers side is a fuse box. Open the plastic cover and you will see several relays. Your local auto parts store should be able to test the relay for you.
