When i placed the new battery ...car won't even crank... interior light doesn't work.. completely no power... the only thing that works is the hazard lights...
Need help... please... please..

 

bump

 

check your alternator,ground connections,fuses..check all your electrical connections while your at it make sure everything is connected properly..good luck

 

If you're main relay goes will this happen?
Thanks..

 

Your Main Relay only makes the fuel pump not turn on. Everything else in the car should work.

Check your fuses first, you maybe have done something to fry a bunch of them. Don't forget the ones that are in the box under to hood also, there is one in there for ignition I believe.

If you give me a list of things that don't work after you've check what everyone told you, I may be able to help you find your problem. I take a course in Electrical Diagnosis in school and will have a Toyota certification soon enough, and an ASE one eventually. So I may be able to help you find if a wire or something got fried.
