My 2003 Ford Ranger could not be inspected today. They said the computer could not read the truck. Said it was proably a bad fuse. How do we know which fuse is for the computer?
You will need to find your ECM fuse, & check it, however most vehicles will not run when it is blown, or you will have many different warning lamps lighting up. This fuse is usually in your relay center under hood, and on some models located in the cabin fuse panel.
