You need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.

Insert the key and turn to the RUN position. There is a small hole in the steering column below the ignition switch. Insert a 1/8" drill bit (or something similar size) and push upward on the retaining pin in the hole. As you do this, pull out the cylinder lock. It should come right out. To reinstall, turn the new cylinder to the RUN position. Again depress the retaining pin and insert the switch into the steering column. Make sure the new switch is completely seated & aligned before you turn to the OFF position. This will let the retaining pin extend into the hole.

on the ignition switch down by the hazard light control you will see a pin hole turn the lock cylinder to run push a small punch eighth inch iI think may bre smaller.then you will be able to slide the cylinder out may have to pry a little. If you don't have the key you will have to drill the pin out.

Remove ignition transformer to reach it. There should be 2 camshaft position sensors on the 5.4L engine - visibly on the front right cylinder head and the other visibly on the front of the left cylinder head. Remove ,Replace, then return ignition transformer.

Ignition relay is probably shot. It is in the power distribution block in the motor comprtment.
