Tesla Wont Start - Need help!

[Restore]

hello, I bought a 2018 Model S off the auction. Car will not start, keeps saying Reducing Power and shutting down. Replaced the Pyro Fuse and still does the same thing. Any ideas of the the issue could be?

Thank you.

Assume this is something you understood when purchasing at auction?

is it a salvage title?

no, its clean title.

Why aren’t you just taking this to Tesla to fix?

If it isn’t a salvage title then it has to still be under warranty...

HV battery may be at 0% and 12v may be low. Is the car where you can plug in the UMC? Put a battery charger on the 12v too.

Sounds like the battery is dead.
Have you tried charging?

Was the pyro fuse blown?

This is one of those times where full disclosure would help people to help you.

Replacing the pyro fuse as a first step and not just getting Tesla to look at it under warranty might suggest that you've got a car with either crash or flood damage.

Knowing what sort of damage you are facing would help people give you better suggestions rather than assuming it is just a normal 2018 that isn't starting for some reason...

Do please understand this is not because we have anything against buying crash/flood damaged cars or even salvage titles, but it is about trying to actually help you rather than making wild guesses based on inaccurate assumptions...

The message you’re getting could be (among many others) -

• Contactors detected as having a problem
• Low main battery pack charge
• Main battery temperature issue
  
• Many others...

usually there are a string of messages from what I’ve read.

yes it was. I replaced it.

Have you tried charging?

It will not allow me to charge it. Wont open the charge port.

I did take it to Tesla, they wanted 4k to fix it and no guarantees that it will fix it. So I want to try to fix it my self. Yes it has warranty but they said the accident it had caused the issue. but they will not tell me the issue or what needs to be fixed. total BS

 

[brkaus]

Please tell us more about the accident. Visible and suspected damage?

Depending on the accident they may not know until they get in there, but this is why it helps to know the whole story, not just 'Tesla won't start' - would never have suggested warranty work if you'd said it was crash damaged.

How bad is the damage and where?

The reason I did not write the whole story, honestly I didn't think anyone would respond on here but here it is.

Bought the car at an auction, all I saw on photos was the wheel damage. Then I pick it up and noticed that high voltage wires running from the front junction box to the rear high voltage junction box were slightly cut open by the wheel hitting them on impact. so first attempt was to fix the wires up witch I did, still nothing changed. Then I discovered that it has a Pyro Fuse. So I took that out and fixed it and still nothing changed. Now I replaced the wires and still nothing has changed, tomorrow I'm getting a new pyro fuse to see if that will fix anything. That is where im at now.

just added some more details above

The pyro fuse can be tested with an ohmmeter. I don’t *think* it would partially fail.

You put a new 12v battery in it?

did any of the cooling system get damaged?

motors?

I did not put a new 12 volt battery in it. The car has 2000 miles on it and the battery seems to be fine. nothing else got damage but the wheel and the knuckle, since it got pushed back It cut open the two High Voltage wires and that most likely blew the Pyro Fuse. everyone else is working properly.
