Pump appears to be working fine good air intake, will not build up pressure. I have replaced the check valve, and regulator.
Hi Pat. Welcome to you. Thanks for visiting my site and for writing in.
I've moved this question to the "My Compressor Won't Build Pressure" page, as it is certainly a common problem.
I'm not sure why you replaced the regulator, as that only affects the air as it leaves the tank and heads for your air tools. Did you mean, by chance, the pressure switch?
Compressors won't build pressure for a number of reasons. Mechanical, air leakage, misplaced gaskets, failing motor... all of these are addressed in the questions and answers at the end of this page. Why not have a read and see what sounds like your compressor?
Wont build pressure beyond 50-60 lbs and motor keeps running

On this "compressor will not build pressure" page there is a link entitled; "I've just added a page that summarizes many of the answers about why a compressor won't build pressure. That page is right here."
Did you get a chance to look at any of the items that are listed on this page.
It would be helpful in diagnosing your compressor problem to know what you found.
