Ok, i had the diodes in my ecu replaced with some light globes and diodes to allow me to find the short, i chased all through my wiring etc for the short but found nothing, after 3 days in it i traced the short back to the ecu, as it turned out this is what happened. I disconnected the autronic ecu power wire so i could crank the engine to build oil pressure before i started it. The autronic tried to pull its power through the shared sensors etc seeing its a parrallel ecu install and torched the diodes and the circuit board creating a dead short between the etcs power pin and the chassis ground pin. I bought a used ecu and key, put my ecus back to how they were before i started the conversion and disconnected the crank sensor, bought a new battery and cranked it until i had oil pressure then fired it up. Its alive..... unfortunately the 2jz gte etcsi throttle body i bought isnt working so the dbw is in limp mode so thats my next diagnostic task, i also have a premium japan manual throttle convert kit to install but i want the dbw working to control idle before i install the kit as it will be easier to diagnose with the dbw working as factory intended.
