My LX470 has had a starter problem for awhile but after a few trys it starts so i just keep with it and never changed the starter. Normally i turn the key and if the car doesnt start i hear the loud click sound. A few nights ago i turn the key and no click. Almost no sound what so ever. Just a small hissing sound which i figured to be fuel related. At that point i assumed my starter was done so i had the car towed to a mechanic. The mechanic took off the the starter to get it rebuilt and he told me that it was not possible so he has to purchase a new one. Upon completion of the new starter we put in the key and turn it... still nothing. nothing but the same light hissing sound. NO cranking or clicking. What can it be? there has never been a problem with the car other then the starter clicking. any input or advise would surely help for i am stumped. thanks in advanced.
