PO410 Secondary Air injection system malfunction

There is a blower under the battery tray that operates for about 2 mins at startup. The system also has a SAS valve located on the engine near the firewall (round device with a purple vac hose), a relay down near the blower and a small controller on the inside of the radiator shroud. One or more of the 4 components is probably bad. Check the blower by unpluging it from the relay (blue wire I think) and applying 12 v to it. If it doesn't run, that's your problem. They aren't cheap. FCPGroton sells them @ about $300. If the blower runs, your problem is in one of the other three components
