P0410 does indicate a fault with the secondary air injection system. If the
problem is in fact the fuse you will not find it in the fuse box. There are
two fuses which belong to the Air Pump located near the battery. One should
be a 30amp in-line fuse and the other a regular 10amp in-line fuse.
To make sure that the pump is not working before checking the fuses you
should disconnect the hose running from the air pump to the top of the
engine and on a cold start check to see there is air being pumped through
the hose. If there is none, either the pump for fuse is defective. Since
you've already replaced the pump there's a good chance one of the two fuses
are blown.
The defective vacuum switch can also cause a P0410 fault, but once again
since this part is new as well we can lean on the fuses. Good luck.
