Hello I have a 2007 Toyota Highlander with about 182k miles on it that doesn't start when I turn the key. The power turns on but when I go to start the car everything shuts off. I've checked the battery and made sure it's grounded. I've also changed the starter so it's none of those. Can you please help?
Relays and fuses all work and there is 1 click before everything stops working
When you turn the key, is the security light off?
Before turning the key it's on when I go to crank it all power stops
You may have a bad fusible link:

I'll check it when I get off and before I go home if it is the problem I will let you know
I can't even find the fusible links on my car I checked near the battery where the guys was and it's not there
You should find the 140 A fuse:

I checked all relays and everything is good
Do you have 12.5 volts at the battery with the car off? How old is the battery? Have you tried to jump start it?
Its an 8 month old battery and it works perfectly until I try to crank it which everything then shuts down
I wonder if it could be a bad transponder key. Have you tried using a spare?
I got the car with only a single key for it so I don't have a spare
With someone holding the key in the start position, tap on the starter motor with a hammer. If it turns over, you need a new starter motor. If not, suspect the ignition switch.
I put a brand new starter in last week or so I'm thinking it may be the ignition switch or some wires messed up somewhere
If the car starts with a jump, suspect the battery is not getting properly charged due to a bad alternator.
It doesn't start even with a jump too kthe battery to get tested and it was good
I'm sure you know, one key is not a good situation, car running or not. Maybe a local lock smith would have the equipment to check your key and possibly make a new one for much less than a dealership.
Have you tried jump starting it like @doc asked?
Sorry, I see your response now.
