I have a 91 mazda 626. Several months ago I replaced starter, ran great. Just recently I had to jump start it. Went had the battery checked, that was fine but was told altenator was bad, replaced that and gave it a jump to start. Once I turned off wont start anymore. Before all this I was having problems with my headlights coming on by themselves or while driving at night the brights would just come on. I was told it might be in my ignition switch. Would a faulty ignition switch have anything to do with no power but my lights, dash and radio will come on just wont start. Any advice or suggestions would be greatly appreciated. I'm at a lost.
