When I first install my key into the ignition tumbler, I have power and all the lights and buzzers go off. When i turn the key to start the truck it clicks and then i lose all power. I've replaced the key tumbler asembly. I'm thinkin it might be the ignition switch but, I'm not sure how to replace it.

I am trying to track down this same problem. A friend of mine had this happen in his 1993 F-150 and it was a split in wire insulation where it passed through the firewall and it was grounding out. I have not had a chance to look at this yet. We might be able to bypass the ignition switch by jumping the posts on the starter relay behind the battery on the right fender and see if that has an issue. I will also check the connection to the alternator.
