MY car wont start without a jump.
i recently changed the alternator and battery about 5 months ago,all brand new. it wont start now,anyone got any ideas? I'm pretty sure the battery and alternator is good it has not been a year yet..and these are all AutoZone parts. Any help would greatly be appreciated thanks

 

i forgot to add the brake and the abs lights come on. no battery light on when driving or check engine light

 

Very vague, but let's get the ball rolling.
Car year?
When it doesn't start, any lights? Turn the lights on and try and start the car, lights yes, then dim when turning the key to start? Yes, battery.
Have the battery checked as even a new battery can go south. If battery proves fine, have it charged, install with clean cable ends, then you'll need to check for a drain when the cars is off.

It's a start.

 

its a 2005 TL
when i turn the lights on it wont start or lights off.
i took it to autozone and they said to check my grounds?
They all seem connected to me.
tom i am gonna see a mechanic to see whats wrong.
you guys got any ideas?

 

could be a short somewhere...
