OK what im asking is can you check for leaks with the UIM off by using the F/P and ground connector thanks alot for those that can help

 

You'll be able to check for leaks in the lines and from the rails to injectors, but you won't be able to tell if the injectors are properly seated to the block as they won't fire using this method

 

you can look down the lower intake manifold and see if the secondary are leaking. Take a paper towel and stick it down the manifold and check to see if it get's wet when you pull it back out.

 

you all have been a good and great help my next feet would be to take the injectors out, do they screw in or just pop out i would like to do this work on my own i will never take it to mazda to fix so if you can share this info it would be great thanks
