99 suburban LS 5.7l V8 secondary air pump stays running
Started with the p0410 trouble code. Pump was seized, so replaced pump along with the check valve and hoses. Ran fine for about a day, then noticed pump was running when I passed by the vehicle. Unplugged it, plugged back in, and all seemed to be fixed. Now the check engine light back on, and again the pump stays running- vehicle turned off and key removed from ignition. Have to go borrow a code tester again, but wondering if anyone has any idea what is causing the pump to stay running? I don't want this one to burn up. I need to get it smogged for my reg renewal asap before I get penalized for it being late. Any help would be much appreciated, because the guy who replaced the pump and did the unplugging thing just wants to reset the codes and try again. I'm thinking there is a more logical reason or a step he neglected to do when replacing the pump. Thanks.

Does anyone have the troubleshooting steps to test the relay to make sure that is indeed the problem?
