If I have an issue I usually start with whatever I touched last. Go back and double check all the lines on the relay valve. Make sure nothing is leaking and all the lines are connected back the same. A line in the wrong spot could ruin your day. It’s easy to do when you’re frustrated and something is hard to get to, ask me how I know! 

BTW when I did mine I did pull the entire relay valve down like you did and not until then did I realize it was just the exhaust port, so I was in the same boat as you. I do remember some choice words of encouragement to get it out and back in, luckily the orange trees nearby did not blush!
