brz no crank and no power to starter
 

my 2013 brz push button wont crank everything in and out of the car works (gauges,lights etc) also the starter,battery key fob,ecu,fuel pump and clutch switch are all working or have been replaced.

ive visually checked all the fuses and relays and switched some around with ones that i know worked but still have no power to my starter any ideas what is could be?

mods:
header back exhaust
tail lights
led fog lights
sub woofer
oft tuner
rocket bunny rear diffuser

Did you check for codes? Direct wire the starter with the ign on to test the starter?

Check live data in obd2 if it shows clutch switch, etc. I never checked on these cars for that..

could it be the security immobilizer, check the info in this thread to rule that out:

No codes like engine lights or anything but the dealer said I had fault codes in my ecu (probably from the starter circuit) but I got a used ecu for 100$ and got it flashed into the car and still the same thing is happening.

And where is the immobilizer located and how would I trouble shoot it?

I gave you a super handy link to the forum thread that should be able to answer most of your questions regarding the immobilizer, the member who posted had a very similar issue that you describe, check out the link below:

update
 

i just want to point out i had the exact same issue 4/5 months ago the only difference was if i kept pushing the push button the car would eventually start and when it did i got a engine light with a P0512 code (i dont think its my push butto cause it cycles on accessory and off no problem) i didn't mention this before cause i couldn't remember what code came up cause i cleared it and never had the issue again. but it was for sure P0512 i dont have an engine light this time around but i think thats cause i haven't got it to start yet.
