on the 4.3l version the knock sensor is on the back left side of the engine right by the bell housing. on the bigger engines they are below the intake manifold in the engine valley

Not the igniton switch, its the ingition cylinder and or the housing. The switch is not part of what you are really turning. It's connected to it via gears. The common problem is the key gets worn out and the tumblers wear also. Eventualy they do not line up right and will not make the "bar" drop in the cylinder to allow it to turn from the off positon. If you have the title in your name and the key has never been rekeyed or the code has been changed you can go down to a dealership with all of the info for the truck and they can cut you a key from the vin number. You can try that first before you put a cylinder and housing in it.

Remove the radiator upper fan shroud,
Remove the serpentine belt,
Place a drain pan under the hoses to catch the fluid and remove the and remove the hoses from the hard lines coming out of the pump, making a note of which is which, stuff the end of a clean rag into each hose to prevent anything from getting inside it,
Using a pulley removal tool, remove the pulley from the pump,
Remove the four bolts from the rear of the pump( V8 has 4 bolts,V6 has 2 bolts ) and lift the pump out.

Bleed the system as follows,
Wheels straight ahead,

Check for leaks,
Re-check the fluid lever and add more if needed to keep it up to the Cold mark,
Move the steering wheel from side to side several times WITHOUT hitting the stops, this will work the air out of the system, keep adding fluid if needed during this process,
When the fluid level stops going down the system should be free of any trapped air,
Set the wheels straight ahead again and allow the engine to run for 5-10 minutes before shutting it down, re-check the fluid level,
Road test the vehicle and drive it long enough to get it up to normal operating temperature,
Re-check fluid level and fill it to the Hot level.

There are 2 knock sensors on these motors. They are located in the valley cover under the intake manifold.
You will have to remove the intake to service them and to even be able to see them.
