Sounds like you have the wrong pump wire tapped..... Make sure that it's the one closest to the engine in the "upper set"

I found the problem. It was I had the green wire grounded. That is the map line. But now I find out that I have the wrong blue box. It is for a freightliner or rv. Acording to blue chip It will set offf alot of codes in my 2001
