Thank you for your reply..
First of all, you can yank the fuse for the secondary air injection system and disable that damn pump! (The one Max is talking about.)
It is fuse 4, the ONLY 40 amp fuse on the Relay Control Board - if you yank the fuse, the pump won't run. Period. Now it WILL generate a new code for the secondary air injection system (P0401 or P0410, I can't remember which - just ignore it. Not having secondary air does nothing but leave the CATs cool longer at startup and generate that code.)
If that clears the issue, we can go from there - it could be a stuck relay on the RCM or some other issue causing the relay to pull in when is should not...
Take the cover off the big box next to the battery, the RCM is the module closest to the center line of the car - lift it up and find the 40amp fuse and yank it out. Set the module back down in there and put the cover back on and see what you get.
