2005 Lexus ES 330 wont start

There's two common things to look for. First, a lot of manufacturers use the larger starter terminal as a convenient tie point for other circuits and attach a second terminal there over the top of the terminal for the battery cable. Look for a wire hanging there that you forgot to attach. Second, you had to disconnect a battery cable for this job and you will have disturbed a connection that causes a lot of trouble on all car brands. Follow the smaller positive battery wire to where it bolts to the under-hood fuse box and be sure that connection is clean and tight. Less common, but while you're at it, follow the smaller negative battery wire to where it bolts to the body and be it isn't loose or corroded.
