My Problem and solution was previously posted. I jiggled the + shaped flow valve that the water filter pushes in. Turn off and relieve water pressure before changing the water filter seems like a good idea.
The filter head assembly has a nipple sticking out in the spot that water will come into the filter. This nipple will be pushed out by the water pressure behind it to stop the water coming out when there is no filter mounted.
When you mount the filter it will push that nipple in slightly and allow the water to flow through your filter, in this process you can damage that nipple and it will not be pushed in, so water will not flow(or flow is reduced) unless you change the filter head assembly.
Solution: before changing the filter shot off the water AND eliminate the water pressure by turning on a cold water faucet.
This way your filter will not damage the nipple in the filter head assembly.
