MIL on dash lit up recently and gauges OK
Tried scan from parts store and got no reading.Was told it was fuse,next scan cannot read any code.Must I check EVERY fuse ?

Many times the MIL will come on with no change in performance. The ability for these systems to detect a problem before it becomes a problem is really good, but you should have the codes checked so as not to make the problem worse.
