I have a 99 saturn which hads a code on it ( p0410 ) the secondary air injection pump. I've changed the one way check valve and I'm told that the pump itself dose work. But apon further inspection of the pump I can tell that the pump only works when u start the car up. And then it'll run for about 15-30 sec. And then cut off and dosn't seem to come back on. Is this normal?

Yes you will hear it come one when you start the car for like 30 second's. So you changed the valve that is on top the a/c compressor that has a line going to it from the vacuum solenoid?Have you made sure the vacuum source from the intake manifold is good going into the vacuum solenoid.

Yes all lines seem to be good, as long as the pump is working, all of 30 sec. After that there's nothing. How dose the system work. Dose it pump or dose it recycle

So did you replace the combination valve on top of the a/c compressor?I posted the trouble tree for code P0410 here is the code description.
DTC P0410 determines if the Air Pump System is operating properly. During air pump operation, the PCM monitors the oxygen sensor output. The additional air pumped into the exhaust manifold causes the oxygen sensor to indicate a lean condition in a properly operating system. If the oxygen sensor does not indicate a lean condition for a fixed amount of time, it will fail the DTC P0410 diagnostic test.

DTC PARAMETERS

DTC P0410 will set when:

* The oxygen sensor does not indicate a lean condition during air pump operation.
* No MAP, TP EGR, O2S, Misfire or Fuel Trim DTCs are set.

The diagnostic for DTC P0410 will only run when the air pump is on. If the air pump runs only for a short period of time, the P0410 Diagnostic Test may not run.

DIAGNOSTIC AIDS
Use the Scan Tool Air Pump Special Test to verify if a problem exists. The Special Test turns on the air pump for 30 seconds and forces the DTC P0410 Diagnostic Test to run.
