Ignition Switch

Removal

Disconnect battery ground cable.
Remove the upper steering column shroud by removing the self-tapping screws.
Remove four bolts retaining lower steering column shroud and remove lower steering column shroud.
Remove lock screw and disconnect the ignition switch electrical connector.
Rotate the ignition switch lock cylinder to the Run position.
Remove the two screws retaining ignition switch.
Disengage the ignition switch from the actuator.
Installation

NOTE: A new replacement ignition switch assembly will be set in the RUN position as received.

Adjust the ignition switch by sliding the carrier to the ignition switch RUN position.
Check to ensure that the ignition switch lock cylinder is in the RUN position. The RUN position is achieved by rotating the ignition switch lock cylinder approximately 90 degrees from the LOCK position.

Install the ignition switch into the column actuator hole. It may be necessary to move the ignition switch slightly back and forth to align the ignition switch mounting holes with the lock cylinder housing threaded holes.
Install retaining screws. Tighten to 6-8 N.M (53-71 lb-in).
Connect the electrical connector to the ignition switch. Tighten lock screw to0.8-1.3 N.M (7-11 lb-in).
Connect battery ground cable.
Check ignition switch for proper function, including START and ACC positions. Also, make certain that the column is in the LOCK position.
Install the upper steering column shroud and lower steering column shroud.

Does it turn over or not turn over? If not, check for power at the gray/white wire coming off the ignition switch. If nothing there, you may have a bad switch. Also check fuse #40 in the underhood power center to be sure it is good

No it does not turn over. Was told we have to take it to dealer to have the computer reset. Due to the ignition code and computer do not match. But were trying what u have suggested.

So you replaced the tumbler, not the actual electrical ignition switch? That would/could expalin the need to have it programmed for the anit-theft to recognize it.I misundersttod what had been replaced.

My car wouldnt start one day, just out of now where it wouldnt turn over, so I was told it needed a new ignition switch. So I ordered one, took old one out and replaced it. If you jump start from syleniod it will turn over, but still will not start. Thats when I was told I had to takwe it to the dealer to have it reprogrammed. I really dont understand that, if the key fits it.

So you didnt replace the part where the key goes? Test the wire I mentioned previously to see if you are getting trigger out. Also check for 12 volts at the small wire on the starter solenoid. If you have 12 volts at the small wire when key is in the crank position, the starter is bad. Have you tried swapping the starter relay for another of no importance as far as running the car like the wiper or a/c relay

Yes we replaced the part where the key goes, they said it was an ignition switch. But now I found out it is called a tumbler, so we have new keys and door keys. Like ive said when you turn the car on everything inside works, power windows, sunroof, radio. But it will not start. So I guess I will have to have it towed after all, to a dealer to reprogram the computer. Thank you.
