Remove both battery cables, clean them with a wire brush, clean the posts with a wire brush.

Check to make sure the -NEG ground cable is tight at the chassis and engine block.

Charge the battery. Reconnect the cables to the battery and try it again.

Hello

I did remove both negative/positive battery cables and reinserted (3x)
I went to autozone and had the battery re-charged.

- Check to make sure the -NEG ground cable is tight at the chassis and engine block -
(where can I check/ look for the chassis cable?)

thanks

 

Try hitting the starter? Could be on the way out.

 

where do I do this... I tried to start the car but it would only make this " single click sound"
but car would not start.
How would i know if my starter needs replacing?
if starter needs to be replace, do i need to bring the car to shop? i only have tracspec service my car

Thanks

 

You have completed checking the easy stuff. It's possible the starter solenoid plunger is activating when you press the start button, but the plunger contacts are worn or corroded to the point the contacts will not carry enough power to energize the starter drive and spin the starter motor. The solution would be to remove the starter and have it tested, or have the car towed to the your shop and have it repaired.

 

The GGLC parts x-reference shows multiple starters. Scroll down to section M.

How hard is it to replace the starter (new starter unit)
Does the car need to be lifted-up?

 

Starter is on the top-side of the transmission case, so it doesn't need to be lifted. It's held in with 2 bolts and a clamp. Time book shows 0.8 hours for renew.

 

Hello

So I haven't use the car for maybe two weeks, just today when I tried to start the car
after inserting the key to turn the car ON, it would just make a single "CLICK Sound", but the
car would not start. The battery is OK, lights, power windows etc., all work.

This is the first time this has happened. My car has never had any issues. Its well
maintained.

What could be the issue?

Thanks

99% chance that your battery is simply too weak the start the car. Here's why it clicks. Powering windows and fans takes nothing, starting the engine takes hundreds of amps.

Your battery is nominally 12 volts, when you start the car, it puts an enormous load on the battery, and the voltage drops - a healthy charged battery will drop to somewhere around 9V when cranking the starter. When the battery is weak, the voltage drops further, and at some point, it drops below the activation voltage of the starter relay, and it clicks open, you hear one click. When it opens, load is removed from the battery and the voltage increases, past the relay activation theshold, and it clicks again, and this repeats. Click-click, on-off.

Charge your battery or jump start it, it'll crank right up most likely.

Jumping the Evora is not recommended, as it has led to some cooked ECUs.

 

If you are not overly comfortable working on your car, the easiest change would be the battery first. Although as mentioned above, the starter is not that difficult. However, just tossing parts at it may cost you extra $.

With that said, how old is your battery? Besides getting it charged at autozone, did they test it? I change my battery out every 3 years even though I keep my car on a tender 100% of the time that I am not driving it. I look at it as cheap insurance. Newer manufactured batteries don't seem to fail like the old ones- the older ones used to kinda slowly crap out. New ones just fail unexpected. So, if you have an older battery, it might be wise to swap it first as you may need one in the near future anyway (if you do install a new one, make sure its fully charged before being installed).

If you try to jump start your Evora, be certain the key IS NOT in the ignition until the jump battery is hooked up. As mentioned, an electrical spike with the key in the ignition can fry the ECU. (The safe bet is to not try to jump start.)

Here's a video that shows some info on how to replace the starter:

Here's info on replacing the starter brushes:

Replacing Starter Motor Brush Yoke

wanted to document this for others - realtively easy job and replacement brush yoke and brushes was $16.85 from eBay Starter motor was easy for me to access as I have the Radium CAI and the stock air intake box is gone Disconnect the battery Disconnect the stater motor main lead and solenoid...

Great post from @2011 chrome orange, as usual.

Basically any auto repair place should be able to verify battery health. There is one easy way to test if it's the starter. You can push start the car. It's not glamorous, but it's pretty safe if you have a little bit of room. It should fire right up, even cold.

I'm going to make a wild prediction here: was the heat chimney tube, by the rear window, cracked at some point? A lot of early starters failed and I'm convinced it's water getting in that tube.

Theres a little flake but i did not see any cracks on the tube

 

Not normally recommended to push start any car with a computer.

A battery analyzer typically works, a load test is less. Your battery is older than 4 years. Was it cold last week?
Just replace it

Sorry to go offtopic: Recommended by whom? Is the concern electrical or mechanical? Neither should be an issue with the manual Evora. There's no electronics in the drivetrain that would make it any different than hitting the ring gear on the flywheel. My biggest concern would be driving into something once it catches.

EDIT: to be clear, this doesn't work well with a dead battery -- only with a dead starter. That's what I was suggesting we verify.

I just had this issue with my 2017 a single click and upon trying to crank it again and at some point the screen was blanking out. I tried about 20 times and always the same single click. I thought it was the starter but I decided to hook a battery charger to the car first. Initial connection showed about 12.4v I believe and said 60% so I let it charge to 14.4v 100% and the car cranked just fine. Drove the car that day then let it sit for a few days and it cranked up fine again though it did have a wrench icon which has since went away I think it needed a few cranks to clear.

When i crank it up the screen does not blank out
Just that single click sound

 

Yeah, do the easiest thing first, before trying to replace starters or whatever, and that means, starting the car from a known good battery. It only takes a few amps to power lights (~8A) or fans or whatever, and it takes 100's of amps to turn the starter. For jump starting, if you want to make it safe, just connect the two batteries together, leave them like that for a little while, then try to start it. If you have a bad starter and a strong battery, you're likely not going to get click-click-click, because voltage won't sag as much, then you look at your starter.

 

i just bought a new battery , and the same thing happened. When I turn it on , its going to make a single click sound but the car will not start....
Just the same thing with the old battery, the guy at autozone testedthat battery and said that battery is 100% good , but i said i still wanted to buy a new one, so i did, and the very same thing happened...i just wasted my money...

 

@cfg_77 I'm sorry I thought your battery was 4+ years old. I have done that myself...

 

no problem, i guess i need to buy that monkeywrench starter...

 

Did you try the tapping on the starter as suggested? If it solves the issue, it won't be a permanent fix but may buy you time until you get a replacement.

 

I will try it tomorrow...

 

Just be careful where you tap. Even though the positive lead has a cover on it, you definitely don't want to hit that and an adjacent metal part if your battery is still connected.

 

Good point. May be better to use a non-conductive item such as wood or a rubber mallet especially if tapping blindly.

 

Back in the orig post it said the car sat for 2 weeks. Mine will barely start after 5 days without being on the battery tender. I'd go new battery and put it on the tender if not driving for a day or 2.

 

OP stated he disconnects battery clamps when parked. That should help avoid quiescent drain. I think a disconnected battery in good condition would retain its charge after sitting for 2 weeks without needing a tender. Having one connected though wouldn't hurt.

 

If your starter needs replacing, it's a great excuse to install a CAI.

 

+1 on the battery. It can have enough juice to work the electrics but not enough to turn the starter. I suggest replacing it and adding a charger that you can easily connect when you are not using the car. Also suggest checking the earths- aluminum is a great conductor but I have seen evidence of galvanic corrosion where the earth strap and bolts connect to the frame.

 

He already replaced the battery seems like from earlier thread. Curious to see if tapping on the starter helped. Unrelated to Evora, but had my wife's Armada doing this while we were out and it was driving me crazy. Tried the NOCO charger. Was underneath knocking on the starter. Sat there perplexed looking at the dash and saw a flashing red key. Ended up being the immobilizer on that car and my key wasn't disabling it.

Not implying that is the case here, but if you have the second key. Worth the two mins to check.

 

So i just had tracspec fix the car... and all the while
I was connecting the positive wire to the negative terminal of the battery....😁...

 

how this didn't result in a bunch of cooked electronics is beyond me. But glad you got it sorted.

 

That's called dodging a bullet!!

Glad it was a simple (and basically no cost) fix and you got it sorted.

I am going to LABEL the wire battery connector ASAP😄
I am also very lucky TRACSPEC AUTO is in fremont, near where i live...Jon is the best!!!!

 

Does anyone know what the difference in the starter is between an automatic trans Evora and a manual trans car? They have different part numbers.

 

MWR likely knows, as they carry aftermarket starters for both models. If it isn't the mounting bracket, then it's probably a slightly different orientation to clear something else.
