I think it is exactly what John said. It clicks only once when I turn the ignition and I talked to a couple other people and they said that it's the contacts on the starter. So it looks like I will be crossing my fingers to get to the weekend and pull the starter. I know the contacts are cheap and a starter is not so cheap but do you think that while i'm at it I should go ahead and replace the whole starter? The truck is 10 years old with 124k on it and starters don't last forever.

Thanks again for the help.
