Secondary air injection pump or relay
This comes from identifix
Here are some test procedures
Test for power at the connector and check relay first
1. Ground the White/Orange (WT/OG) wire at pin 70 at the Powertrain Control Module (PCM) with the key on and see if the air pump relay and air pump operates.
2. If the air pump doesn't run, check for battery voltage at the White wire at pin 5 (with pin 70 still grounded).
3. If voltage is present, access the air pump in the front corner of the Right Front (RF) fender and see if battery voltage is present at the pump on the White wire (with pin 70 grounded at the PCM).
4. If voltage is present at the pump, verify the ground circuit (Black wire) is in good condition.
5. If the power and ground circuits are OK, but the pump does not run, replace the pump.
6. If the pump runs after pin 70 is grounded at the PCM, start the engine. Monitor both upstream O2 sensors after grounding pin 70. The O2 sensors should indicate a lean signal immediately.
7. If they do not, then check the operation of the diverter valves and solenoids. Also check for signs of a damaged vacuum line to the solenoid.

Where are these diverter valves and solonoids?

You've already done steps 1-6? Worry about steps 1-5 and I'm positive you'll find your answer their. It's either the pump, relay or wiring issue

Jump the relay and see if it kicks on
