Hello my name is ***** ***** thank you for your question.
When you turn the key to the ON position, does all the dash warning lights come on?
Well, we are going to need to do some checks to see what is going on.
First where did you get this ignition switch you installed?
The switch sounds like it may be wrong if you got it from a auto parts store. Which would explain your issue.
Do you have the old switch?
This was a complete ignition?
with keys and everything?
Oh the back part of the ignition cylinder assembly, there is two screws that keeps the electrical part of the switch to the ignition. Please remove that from the old ignition cylinder and unplug the new one and plug the old one back in. Then take a screw driver to turn the plastic part of the switch and see if the engine turns over and starts.
You got it. I will be online tomorrow as well.
Just make sure that if the factory electrical part of the switch works, insert that into that new after market one. If it doesn't insert, that just verified that you got the wrong switch. Keep the key in the ignition with it in the on position if you are going to drive it. This way the steering wheel won't lock on you when driving.
Talk to you tomorrow.
Ok then. Well, it looks like we are going start to get into it then.
Can you let me know when you are by the vehicle to do some checks? Also make sure you have a Volt Meter and Test light and I guess some basic tools. Screw drivers 10 mm socket and ratchet.
You got it.
I am here..
I forget, the dash warning lights, they all come on when you turn the key ON?
ok then.. Let me get you the starter wiring diagram so we can try to trace out what is going on.
v6 auto trans right?
That is the wiring diagram. Please start by checking the start signal fuse and see if that fuse is getting power when the key is turned to the Crank Position.
Then lets check power at the gray plug at the starter to see if you have power when the key is turned to the crank position.
Take your time. I will be here all night
Ok. Let me know
First off, the bench test you can never trust. Of course a starter or a Alternator will pass a bench test. There is no load on it it!
All I need you to do is check to see if the gray plug to the starter is getting power when the key is turned to the crank position.
If you have no power to the starter from the gray connector, we need to check the PNP Relay. Also, do you know if you have a after market alarm or remote start in the truck? They tap into this circuit to keep the starter from starting.
Let me know
Need to see if Pin 2, Pin 5 is getting power at that relay
I am out right now. I should be home in a few hours. Can we continue then?
If you remove the relay and jump pins 5 and 3 does the truck start?
Really? Pin 5 had power?
You had a blown fusible link didn't you?
Is the truck dead with no electrical power?
Lets double check pin 5 for power at the PNP relay. To see where pin 5 is, when you remove the relay, if you look inside where the electrical pins are on the relay, you will see numbers that show the pin layout.
Pin 5 should have power when the key is turned to the Crank Position.
