Hey ya'll. I have a 2007 Lexus ES350 with 173K miles on it. I hadn't driven it much over the past few months since getting a newer vehicle. Over the past few months, I did have trouble starting the car. I would have press the push start button multiple times to get to crank. Being busy with work, I didn't think to replace the battery or starter at that time. So it has been sitting for 3 months. Last week I had some free time with all these Coronavirus going on. So I went to take it for a spin. I got into it and tried starting it up, but it wouldn't. When I press the brake, the push start goes from orange to green, but it doesn't start. There is no clicking from the starter. Just silence. I also noticed there is a Check VSC with traction light on dash. To focus on why the car isn't starting I checked the voltage in my battery. It read low. Battery was a few months old. So I knew the alternator was the culprit. I replaced the alternator and seeing the starter was the original starter on the car; I replaced it as well. I put a new battery in the car today.

So at this point, I have replaced the Alternator, Starter and Battery. I get into the car, and car still won't start. I check my starter relay, but not knowing exactly how to check the voltage, I went on and replaced it as well. So at this point, I have replaced four things, and the car refuses to start up. I do not hear a clicking noise when I try starting it. Im confused on what else would be an issue with this car. It drives like a champ, but just wont start up. Please help!!!

Check your battery cables and make sure you have a good ground.

Then check your fuses.

I checked my battery cables this morning and both the negative and positive where locked in. I'll check the fuses under the hood and in the car to make sure they aren't blown. Is there a specific fuse I should be looking for?

Not really clear from your writing when you purchased the battery in this chain of events. If it were me I’d put it on a charger and then see if everything goes back to normal.

im sorry. I should have put that in there. I purchased the new battery this morning. I installed it and still no start up or click. Just silence. The Aux comes on but that’s all. Lights inside and outside of call come on too.

I rechecked all fuses and they were fine. None of them are burnt out.

key fob battery weak? put it next to start button to check if that makes a diff
"Depress the brake pedal.
Hold the electronic key close to the engine
switch (within 0.4 in. [10 mm]), making sure that
the button side of the key is facing toward you.
Press the engine switch within 5 seconds of
the buzzer, keeping the brake pedal
depressed."

steering wheel lock needs to be unlocked?

"Make sure that the steering wheel lock is released.
To release the steering wheel lock, gently turn the
wheel left or right while pressing the engine
switch."

I just tried it with both keyfobs near the push start and had the same result: No start and silence.

If no start should check:
Starter
Starter relay
Engine immobilizer system
ECM power source circuit
Fuel pump control circuit

Just for kicks - do your wipers work?

Blexus350

The wipers do work.I replaced the Starter Relay today. How do I check the Engine immobilizer system, ECM and Fuel pump circuit?

I can turn the steering wheel with no problem. It isn't locked. I changed the battery in the key job on 10/2019. I dont use it much to unlock the car. I use the door handles. When you say face the electronic key, Im guessing you mean the key fob right? The buzzer you're talking about, is that sound once you pressure the push start button?

You do have gas, correct?

Blexus350

Yes I have half a tank with premium gas.

I had a similar situation. The car wouldn't start, I moved the shifter from park thru the gears and back to park. The car started after this. Don't ask me to make sense of it.
