My husband and I just installed an amp and speakers in my 2003 F-150 and now it will not start. When we hooked the battery cables back up all the accesories came on even though the key wasn't on but the truck will not start. I think it has to do with the fuses and he thinks he broke the ignition switch some how. Any ideas would be appreciated.

 

Hello and Welcome to the forum!

Did you figure it out? It does sound like the ignition switch broke if all the accessories came on and there was no key in it.
