2008 Land Cruiser Now Won't Start... (1 Viewer)

My wife started her LC this morning to warm it up before leaving for work. She said she came out after it was running for a few minutes and said it was idling really low, then revved up quite a bit. She shut the car off and now it won't start.

I tired to start it. After pressing the start button that was green, it didn't turn over and the green light on the starter button stayed on. Under the hood, I could her a buzzing that sounded like it was coming from near or behind the fuse/relay box behind the battery. (Towards the firewall.) We were in a bit of a rush trying to get to work so that's about the best I can describe what was going on under the hood.

I disconnected the battery since it wouldn't 'reset'. I tried again to start it but same deal.

The car was starting and running normally yesterday and the battery is under 3 years old.

Any ideas as to what is going on?

Would start with the obvious:
Make sure it's not out of gas
Check if battery terminals are loose
Check battery and try to jump start
Test alternator voltage
Check for current draw

If you have the tools pull the codes, check battery voltage, check terminal condition.

Thanks, I will try to jump it, which will help narrow things down. I don't have any way to read codes or do much testing unfortunately.

The battery checked out ok, but needed to charge. I got it charged, and the car started. While running I pulled the negative battery terminal. Car died.

It's going in tomorrow for probably a new alternator.

Thanks everyone for the help! It usually is really back to the basics...

I thought, even with the alternator putting out voltage, the 200 won’t run without a battery.

If that was his alternator test, it was a bad way to test. I would never pull off a battery terminal on a running vehicle.
