if you pressurize the intake and it holds everything, then you need to hook up diagnostics to it and read the fault codes. One step at a time.

Eliminate the simple, most common things first.

When leak testing make sure you properly pressurize the intake.
Visually "checking" is as good as doing nothing.

Ok, I think that's it
