SOURCE: No power leaving the relay

Are you testing the relay when the engine is cold?
The air injection pump works for a very short period of time during initial cold engine start.

Once the exhaust stream is warm enough to support O2 sensor function, the pump shuts off and will not come on again until conditions are met.
Let me know.
Regards,

If you have a "Air pump installed on your TB then you need to replace pump and or check to make sure that the hose's are all connect to it prior to replacing the pump which is dependisng on which engine you have on the lower left side (passenger)
Models Affected
1999-2003 Chevrolet Blazer, S10
1999-2001 GMC Jimmy
1999-2003 GMC Sonoma
1999-2001 Oldsmobile Bravada
All with 2.2L or 4.3L Engine (VINs 4, H, 5, W -- RPOs LN2, L43, L35)
Condition
Some owners may comment on the check engine light being illuminated. Upon
investigation, the technician may find a DTC P0410 indicating there is a concern in the
secondary air injection system.
Cause
This concern may be attributed to water that may have collected in the AIR pump or the
vent solenoid and frozen or corroded the pump.
Correction
Replace the AIR pump and install a new inlet hose and solenoid tube assembly using
the following procedure:
1. Prep vehicle.
2. Raise vehicle on hoist.
3. Remove shield covering AIR pump.
4. Remove hose and vacuum lines from pump and solenoid.
5. Remove AIR pump inlet hose. Do not re-use.
6. Disconnect electrical connectors from pump and solenoid.
7. Remove pump mounting bolts and pump.
8. Transfer isolators from the old pump to the new pump.
9. Install new AIR pump and bolts to vehicle. Tighten the bolts to 17N·m (12.5 lb ft).
10. Route new hose assembly up between engine and fender. It should come up near
the area between the battery and the coolant bottle.
11. Connect new inlet hose to pump inlet.
12. Connect old outlet hose to pump outlet.
13. Connect electrical connector to pump.
14. Connect electrical connector for solenoid to connector on the new hose assembly.
15. Connect the hose with the white nipple to the vacuum source hose.
16. Connect the remaining hose to the shut off valve.
17. Install shield covering AIR pump.
18. Lower vehicle.
19. Remove coolant reservoir nut nearest the battery.
20. Route new hose assembly between the battery and the coolant reservoir with the solenoid on top.
21. Install the solenoid bracket onto the coolant reservoir stud and reinstall the nut
back into the vehicle.
22. Use a wire tie to keep the new hose assembly away from the engine. On four
cylinder engines, tie to the AIR outlet hose. On six cylinder engines, tie to an
available hole in the radiator fan shroud.

It is in one of 2 places. Either in the underhood electrical center(fuse block), or under the truck on the driver side frame rail, rearward of the ABS brake module assembly.

My 2005 chevy trail blazer has code p0410 and i dont know what needs to be replaced provide that i know that it means secondary air injection system but i need to know the part that needs replacement


check the air pump on your trailblazer, make sure its clean inside and the hoses are properly fastened. also check to make sure it works properly by listening for it when you start the vehicle. if the air pump is working correctly, replace the position 1 o2 sensor meaning the sensor on the exhaust manifold. the air pump is located under the vehicle, inside the frame rail on the drivers side in front of the transfer case crossmember with 2 hoses connected to it.

Secondary Air Injection System Malfunction


P0410 secondary air injection system malfunction. I've dealt with this problem myself. It's either the air pump which is located under the driver's side door on the frame, or it's the valve on the engine that is sticking.
The air pumps are notorious for "freezing up" in cold climates due to water sitting in the pump and freezing and then breaking the impeller from the shaft in the pump. This is what happened with mine.
Remove your pump and test it. If it spins and blows air,then it's fine. Then check your valve on the engine. If that opens (which they like to get corroded with exhaust gasses and stick) Then that will be ok. If not, you'll have a pretty good idea what is going on.
I wnt ahead and replaced both the pump and valve, which were both crappy.
GM also has a check valve that you can install to prevent water from entering the pump. I just drilled a small hole in the bottom of mine to "drain" the water.
