If the light doesn't come on, that opens things up. First, I would like you to check for vacuum leaks, check the EGR valve to make sure it is working properly, and if that all checks out, I need you to check fuel pump pressure.
Let me know if you need directions for checking fuel pump pressure.
Let me know what you find.
