what does it mean when... (error code readout)

[Tess McMillan]

So my CEL has been going on just recently after the engine warms up ('88 
80Q w/ modified cam within the last 18 mo.). It started after getting new 
gas. Often my CEL goes on after refueling but it goes away after a few 
hours. This time, it hasn't, so I wanted to see what the error code would be.

I have tried my usual technique of tripping the readout of the error 
codes using a spare fuse, but this isn't working. I don't believe I've 
ever had that happen before.

What does it mean when you can't trip a code readout? ? ?
