Loud Pump on start up is Secondary Air Injection pump, its not actually needed, its just there to lower emission when stone cold. It can be unplugged (its behind front bumper)

Can you do a paperclip test? Get the codes and post them up here, details on how to do it in the maintenance section  :y

There's no suction on the small breather hose, looks completely gunged up. Maybe we've found the problem!!

Thats a breather hose, that blockage would cause cam cover gasket to fail, but not cutting how.

Get some carb cleaner and give the ICV a good clean  :y

Not necessarily true. Even with a brand new IACV, ours cut out occasionally until Grumpy wrote his guide, and I cleaned out that breather jet.
