Hey guys, so I changed my camshaft position sensor on my 1998 GMC Sierra 1500 4.3 and after I did when I was driving the truck I noticed my speedometer no longer worked. It worked fine before I did this. Only thing I know I forgot to do when I replaced the sensor was to disconnect the battery cables....don't ask me why I forgot to but I did. Could I have blown a fuse? What could have caused this to happen?
