Welcome to the forum, thanks for the donation, What model? Does the fuse blow quickly? The load side of asd relay supplies voltage to ignition coil-- injectors-- 02 heater circuits--? I have heard of 02 heater circuit causing problems. Codes don't always set when they should. You can do ohms test on everything, may not be conclusive. Did you talk to the people that worked on the vehicle?
