2004 Tundra won't start

Hi I am a new member and trying to get some help. my 2004 Tundra would not start ......no clicking or anything so I assumed the battery was dead because the night before i found my brake lights had stayed on so i pulled the fuse and the next morning i had the no start problem.I started the truck the night before after I pulled the fuse and it started.So I checked it in the morning and proceeded to replace the brake light switch ( also hoping that the wires were connected to the starting harness somehow.....lol boy was i wrong ) so I went on toyota Tundras blog and everything I read suggested that it was the starter....but I couldn't find anywhere on the blog or websites on how to check the starter to see if i was getting juice other than take it out and test it.....what a nightmare....I don't know on some of the sites they say they can remove the starter in 30 minutes when you have to take the top of the motor apart to get to the starter.....anyway did all that and found that i am not getting any juice to the solenoid wire when the key is in the start position...any help
