I replaced the starter about a month ago. The car started fine about a half dozen times and then stopped turning over altogether - not a sound when I turned the key after the glow plug light went off. Replaced the ignition switch yesterday after first having the starter tested to make sure it wasn't a dud (it wasn't). Started the car successfully five or six times without trouble, but am now having the same problem I had before: nothing when I turn the key after the glow plug light turns off. Any idea what's going on? I'm at a loss.
P.S. - The battery is brand new, and the posts are clean. I replaced the alternator a few months back, so I don't think it's a battery issue. Also, the connection at the transmission housing that prevents the car from starting when not in Park or Neutral looks snug.
