Just installed brand new Costco battery and this am car won't start. I can power on ignition but when I press to start.the dashboard goes dark then lite up again and I cab hear clicking from.front left side but car won't start. Starter or alternator?

 

First eliminate battery as the issue. Check battery connections, clean and tight. Check voltage on battery. Have you tried to charge the battery or jump start it? What symptoms were you having that caused you to replace the battery. Did you have it tested prior to replacement?

 

thanks for the help! Yes I had battery tested before i replaced it and it was dead as per mechanic that just did my radiator swap. Also checked.battery connections and everything looks good. Tried to jump start with cable and another car but in vain. Seems battery is charged when i turn ignition eveything check normal on dashboard but i hear click from lower front passenger side when trying to start and dashboard dies off like it's rebooting.

 

Your starter likely will have to be replaced.

 

Post a picture of your battery.

 

So, I'm trying to read between the lines. Help me better understand.

You wrote: "Just installed brand new Costco battery and this am car won't start." Does this mean that you installed the new battery and tried to start the car soon after and the car would not start. Or, does it mean that you installed the new battery and tried to start it some time later?

 

Without more details such as was the car starting fine after new battery multiple times for weeks or months, then suddenly, the clicking sound? Starters do go bad and a clicking sound is a symptom. Sometimes a good whack on the starter with a mallet will get it working again. But it's tight quarters on this car. I suggest you contact your mechanic. Many here recommend OEM or Denso starter. Avoid auto store generic starters as they are often low quality.

 

at mechanic now waiting for confirmation but yes most likely the starter is done. Now read not to use autozone replacement part and would like to use OEM.denso part but latest version of starter. Does anyone knows Denso newer starter part #?

 

I installed it last week from costco for LS 460 model https://costco.interstatebatteries.c...183&Country=US

 

Costco replacement battery was installed -10 days ago and since car has been working fine hence I lean towards starter vs alternator.

 

Need to see your battery installed in the car.

 

you got it right, car and new battery have been fine for more than a week before this new issue. Completly agree re Denso vs generic but I am stuck more than fifty miles away so we will see what can be done.

 

Mechanic here is saying 6.1 h labor plus starter belt and wanted to do spark plug? What should labor cost starter only approximately? Guy here wants $1400 with $500 parts rest labor really?

 

I would have the car sent on a deck truck to the closest Lexus dealer, a lot can go wrong if you let the wrong person try to fix it.

 

Spark plugs can be addressed at another time. There is no starter belt but there is a serpentine belt for the front of engine. If it's cracked/worn it needs replacement. It can be addressed another time. The starter on LS460 is in a difficult spot that requires more than normal labor. He should be able to show you the "book" hours that is standard practice. If he won't, it may be wise to have it taken to the dealer or your trusted mechanic by truck.
