I hope it's okay to post a problem I'm having with my Lexus RX 300 since lot's of us have secondary cars and could possibly learn from this thread :typing:...

Today I turned the ignition key on the Rx 300, heard one single click, and nothing happened-it didn't start. I tried it once more and same thing. Here's the weird part... round 3- car turns on. I take her for a drive around the block and back, park her, turn her off and back on, again- one click. 2 more tries-nothing. 4th try- vrooom! What could this be?

2 tidbits of info: Last year the car had an idle air control valve problem where it wouldn't start no matter how many times you turned the key until you tapped the gas pedal, than it would start. The mechanic took the valve, inspected it and said it had a lot of build-up on it and said that was most likely the problem, he said I could replace it or he could clean it really good and might last a long time and I went with the cleaning. It's been about a year with no problems and I don't think it's the same symptoms, slightly different. I think this might be more of a starter issue but I'm not positive. Thoughts and ideas please :dunno:

Since you are referring the E39 M5 parts and support vehicle, I think the quesion is allowed!:grinyes:

My first thought is bad battery cable (not just on M5's) or possible issue with either ignition switch or key. Bad ground would also be a low probablity.

Ignitions switches can wear out or the contacts can go bad, but that is usually on pretty high mile cars.
The electronic keys can get a little cranky. If you have another key, try that and see if it makes any difference.

Sound like a bad starter solenoid. Check the starter terminals, ckeck for voltage at the terminals.

A friend of mine has a car like that, starter went when it was 6 months old.

Could also be the battery connections as already said - it's a common fault on lots of cars.

HTH richie.

Haha, that's good. :applause: Thanks, I will check the cables. What's also kinda funny is that I AM using a different key, original electronic key snapped in half where plastic meets metal 2 weeks ago, been too busy to go get new keys, this one is a good back-up key, not electronic. Car has 126k miles.

A-is the starter solenoid and starter the same thing or different? I just need a volt-meter, right? What readings am I looking for?

Thanks everybody. How do I test the starter...what position should the key be in and where should I place the positive and negative points of the voltmeter? If it's anything less than 12 volts that means it's bad?

Starter. My old Buick did the same thing.

It may not be a Lexus, but they were both built for old people. ;)

Don't buy a starter yet, you need to confirm that it went bad. Check all the fuses. Is there a starter relay? Check connection to the starter.

Start looking but don't buy til you test. Also, you might want to for loose connections to the battery terminals, and also corrostion on the battery. My son did some work on my M's and had removed the ground cable while he worked on it. He had put the ground back on to test something, and got busy with customers. End story, he never tighten it down and I drove it home without problems, in the morning went to the gym, then to starbucks,This went on for more than a week, then I go out to start the car to go to work, goes to crank, then nothing. try again and it's just click. Call son and he tells me to check the ground cable. I tighten with those nice tools BMW gives in the truck, started her up and drove to work.

Now you're talking things I don't understand.....(I got fuses and that's it, sorry) , should I fork out some $ for a diagnostic?

Look at the igniton switch first.
Since this is the 3.0L six, you can get to the starter silinoid easy.
The thick wire is the positive from the battery, you will get 12 volts from that. There should be two small wires next to it which activate the silinoid, one is from the ignition switch.
One of them is where you will want to see if the key lights up a test light or voltage meter.

Its not the idle control valve that just effects the intake manifold.

LMAO :M5thumbs:

You're right, I completely, forgot that! Just checked Autozone.com and they do free testing at all locations! By the way if it is the starter, I can get one on eBay brand new for $100 shipped so that's not too bad at all.

How old is the BATTERY!?

Once they start getting low yopu can get funky things when you turn the key...starts, doesn't start, etc.

If it is original, definitely replace it before you do anything else.
