2004 Toyota Tundra 4.7 motor no start no crank

Hello to all. So have taken it to auto mechanic a couple of times and he replaced starter relay switch and fuel pump fuse. Started good for awhile now having the same problem no crank no start. Check all the fuses all appear to be good. One electrical person thinks it may be connected to anti- theft system? Would appreciate any advice am at wits end with this problem. Thanks in advance for any help!!!
