My Escalade 2006 engine is not stating pls what can I do all the function ok.

If I had a nickel for every person on this forum that has replaced their fuel pump... Have testing performed. If your engine is experiencing idle roll, I would suspect an air intake issue or a vacuum problem. But only testing will tell you the answer. Replacing parts without testing is a flat out waste of money, and you could replace a known good part with an inferior replacement part adding insult to injury!
