Doesn't look like it.
It's telling you that you have a P0440 DTC, and that all monitors are reporting "ready". It then appears to be listing all the monitors below the "ready" text.
If I were you, I'd check for TSBs at GM's Techinfo site before doing anything else. Honda's Passport is the same vehicle, and the '98 Passport had an issue with the mis-routing of a particular pipe causing a P0440. Your truck might also have some kind of known problem, which may simplify your troublsehooting.
Thanks, I just had a new fuel pump assembly installed to the tune of $750. Is it possible it could be related? Thanks Don

reset the codes and see if it comes back up.
First thing I usually replace is the fuel cap and/or check for vacuum leaks.
