Does it require taking the steering wheel off if so is it better to take it to a dealer or can I do it at home.
There is a difference between changing the ignition switch (electrical part) and changing the ignition lock cylinder (part the key goes into) Sending you instructions for both. Some of it will be repeated, but you should read both so your sure of what your doing. You can rent a steering wheel puller. If you just unhook the battery and wait 10 minutes, that will disable the air bag, so it is safe to work with. Thanks
See Figures 3, 4 and 5
CAUTION When performing service around the SIR system components or wiring, the SIR system MUST be disabled. Failure to do so could result in possible air bag deployment, personal injury or unneeded SIR system repairs.
When carrying a live inflator module, make sure that the bag and trim cover are pointed away from you. Never carry the inflator module by the wires or connector on the underside of the module. In case of accidental deployment, the bag will then deploy with minimal chance of injury.
When placing a live inflator module on a bench or other surface, always face the bag and trim cover up, away from the surface.

CAUTION The lock assembly is under slight spring tension. Hold the lock bolt in place while removing the lock module assembly.

Thank you for such an in depth answer I believe it is the cylinder lock because we got the truck started by putting the key in and giving it a good whack. If I am off base please let me know.
If everything else was working, there is always the possibility that the starter motor or solenoid was not doing it's job. If it is still dong so it is pretty easy to test the starting system. If not, let me know how far into the tear down you are and maybe we should see about diagnosing some of it first? If the thing still will not engage the starter, see the note below, or let me know what it is doing, thanks
If you are sure the battery is good and fully charged and the cable connections are all good. You will need to check for voltage at the small purple wire on the starter solenoid while some one engages the starter. If you have good voltage at the purple wire and at the large battery terminal both, you will need to replace the starter. If you do not have voltage at the purple wire let me know so we can test the starting system and find where the problem is. I will need to know if it is a standard shift or an automatic. But be sure to check to see if you have any theft or security lights coming on, on the dash first. It may be an issue with the security system also. Thanks, Bob
Thank you very much I will check back with you as I go. I have not started yet I wanted to get answers before I started. I will check the starter first and go from there. You are very informative, and that is awesome!!!
