(i put the normally open wire to the not used port and it sprays... so i put it back to the normally open wire and connect the nozzle to the cold pipe and take it for a spin several times and no meth......IM 100% sure it doesnt spray since my afr stay the same.
what else can i check for? obviously the fuse is good and the pump works... im 97.5 percent sure the wiring is correct... any ideas?
I had this problem. What youneed to do is check all of your vacuum lines connected to your boost source. I had one of my elbows split really bad. So bad that I could hear it while I was driving. The leak was so bad that no pressure was going to the switch so never activating the system. Trust me, look really close. Check all your lines and ZIP TIE THEM!!! Zip ties saved me a lot of trouble.
