Have a 2002 Camry V6 LE. Left it in a parking lot during the day, and returned to find it would not start. I seemed to have lights and the dash lights looke normal on trying to start. I can't recall if I ever heard any real cranking, but it only made a clicking and then a weird whirring sound. I tried to get a jump start, but that did not help at all.
Had it towed that night to dealer. Next day they said it started right up! They ran tests on charging system and ALt putting out 14 v and 81 ampls at idle, and battery has 600 cca during load test. The dealer said they could not find anything wrong (at least they did not charge me anything either....).
I was wondering if perhaps the theft deterent/engine imobilizer sytstem in the car may have been linked to the problem. However, the dealer said that if someone tried to break in the alarm would turn of after a minute or so and reset. Also, not getting it starting even with a jump start is puzzling. Any theories appreciated, Bob K.
