Recently I tried too get my car scanned for a check engine light. (last time it was checked it worked) but now when you hook a scanner up too it, it does not want too link? Iv tried too look into it and people said it could be the cig fuse (that was working) also a B/Burg fuse? (was blown and replaced, still nothing) So I have no idea what too do now too get this too work. Need some help.
