My 2001 Blazer 4x4 has shown a P0410 code. I am wondering if someone would be so kind as to give me steps to follow to fix the issue. Do I begin with replacing the pump first or another component such as a valve or relay? I replaced MAF sensor and both O2 sensors a couple of months ago. Also changed the fuse for the pump just in case but no luck. Any help would be greatly appreciated! Thanks!

Thanks for the advice, I only have til the end of the month to pass the emissions test so I'll try to get to a shop this weekend. I did get ahold of a basic little scanner though, would that be enough to find the culprit? If so, what should I look for? If not then no worries, shop it will be.
THAT WILL ONLY GIVE YOU CODES,NOT WHAT TO REPLACE OR REPAIR

If you had some scan data it would help.
Hey thanks for the reply, I will borrow a scanner tomorrow and get you some data. What info should I gather?
The system fails because the check valves at the exhaust manifolds leak and that allows condensation to collect in the pump and that damages it. Here is some information that will help you. - http://service.gm.com/gmtechlink/images/issues/nov02/TLNov02e.html#story5
Thank you for the reply, unfortunately the link took me to a page that said "Not Found". I guess what I'm wondering is what is the first thing that I should replace to rectify the issue? Or does everything need replacing, check valves, AIR pump, relays, hoses etc..? I know GM released a kit so this kind of thing wouldn't keep happening but I can't seem to find it or the part number for it.
You'll be replacing the valves, the hoses, the motor. GM did have a kit and that link used to outline the whole routine. I'll have to look for another way for you to see it.
Ah, well even if you can't find another way, thanks! I do appreciate your time and help big time.
