You've basically rebuilt the entire valve. The whole top part and the diaghpram are new. That leaves the bottom half of the valve. Did you also install the new solenoid? That could be the problem right there. Or maybe there's some debree in the port. Try cleaning it. Maybe you've pinched the nipple. You could try switching solenoids from the valve next to it and see if it comes on. Good luck!
If I can't fix it, it's broken!
