Several months ago I when I tried to start my 2000 ES 300 I got a clicking sound similar to what I had experienced in some of my earlier cars when the starter or solenoid were bad. So I checked the battery connection and the fluid level. One cell was a little low, but no where near dry—just noticeably lower than the others. I added fluid, tapped the battery terminals gently and the car started right up. A few days later it did the same thing. The battery water was OK and a couple more gentle taps on the battery started the car right up. Later, it did it again. So I checked to see if the lights were dim before I tapped the battery. They were not. Anyway, this went on for a couple of months. 9 out of 10 times the car would start fine.
I left the car with my daughter while I was away on business. I showed her how to tap the battery, which she had to do once or twice. But one day she tapped and tapped but the sucker would not start. She had to have it towed and was told it was the starter.
When I returned, I tried to start it and it would not fire up. So I put it in gear and rolled it a yard or two hoping that would engage the starter. It did not. I tried rolling it again. Still nothing. So I jumped it from my truck and it started without a problem. I started fine (about 20 times) since... until this morning.
The car has been sitting in the garage for a couple of days without being started. It is cold here in Colorado, 20F this morning, though not quite that cold in the garage. When I tried to start it, it did not click as in the past but instead started to turn over (for half a second) then nothing. I turned the key off and tried again and it fired up.
Toyota (no Lexus dealer in the area) says they cannot tell me if it is the starter or not. They have to ‘experience’ the clicking. Is there really no way to test a starter or solenoid? Can the battery be tested enough to determine if it is the cause?
One last bit of info for this lengthy story: Lexus installed a new engine in the car at the start of this year. Old one was bad due to sludge. The battery looks like the original. An 84-month warrantied
