Check all of your vacuum hoses in front and under the UIM. Remove the black pressure chamber in front of the UIM to gain access to many of the hoses. You may have a hose that has popped off. Also, check the green and white check valves to make sure they are working right.

Test the check valve that connects to the pressure chamber.
