LS400 model 2000
It does not starts from the first click in the ignition, it starts after several clicks.
I had checked battery & alternator ...all are ok.
BTW check engine light is off.

what to do?to check?

 

your starter is ready to go kaput, sorry if i am the bearer of the bad news

 

It's very important not to let corrosion set it in on your battery terminals. Once corrosion sets in, your car will randomly fail to start due to electrical contact being lost between battery and cable.
After checking my car' s battery.. i found some corrosion on my car's battery terminals.
I had Scrub the battery terminals and the battery cable ends with a toothbrush. Then i had covered the terminal with some of Petroleum jelly (eg Vaseline or similar) to protect against corrosion.

Now my car is starting from the first click. I think starting problem is solved.

Yep, I guess you should have inspected it closer the first time. Starter is a ***** to pull on this car. I don't think got smart and relocated it elsewhere or made it more accessible in 2000, did they?

 

No they didn't

 

GRANDLS4 just did the starter on his 2.5g LS400, he included lots of pictures too.
