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!
