I changed my fuel pump and car still wont start, cranks but wont turn over, why? on 1999 Cadillac DeVille

While driving to work about a week ago my fuel gauge started to rise and drop and the car cut off, I originally thought I was out of gas so put gas in and after a couple times of turning over the car started back up. two days ago the car shut off while driving again and would not restart I changed the fuel pump and car still wont start and now i here a clicking noise that comes from under the car near the pump as well as under the hood near the fuse panel when car is not started and i dont even have key in ignition. why? some one help please?????

start with basics. fuel pressure check, spark test and compression. one of them will be missing and then we can zero in on the failure. Roy
