I don't have the mode 6 information but if the evap failed, run the purge/seal function.
Monitor the fuel tank pressure while doing so. If you can't pull a vacuum in the fuel
tank, try "clicking" the vent valve with the scan tool. You should here it click when you
command it. Try to run the air pump with the scan tool. Air pumps were a very
common failures on S10's of those years. There is service bullitens out there for them.
They ingest water. They have an updated air pump kit that addresses the issue.
