Re: 91 blazer blowing ecm bat fuse
Welcome to your first post on AF.
The ECM B fuse feeds pcm memory TBI injectors fuel pump relay and fuel select switch and oil pressure switch. First Check the fuel injector wiring where the air cleaner adapter goes over Throtle body. They get pinched there a lot. Let us know how it goes. MT
