My husband has a '98 Camry and recently it started misbehaving. Sometimes it is just fine but twice now it has started up fine in the am then when he goes to leave work it won't start. It clicks on the initial key turn and subsequent trials to start it yield no result. But it takes a jump fine. Suggestions? We know he needs a new car but we were hoping to be able to take our time to find a really good deal.

Do a search for this concern. It's been covered here many times.
It's the starter solenoid contacts that have worn out.
