Each line is a down arrow:
Other than the Evap system malfunction are there any other clues here. Thanks for all your help and assistance Don Smith,

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.
