"I cleaned up the WUR and the lf hole was very dirty with deposit so I cleaned it and use compressed air to make sure that it is debris free."
Can't tell what you mean by this and if you put more than 16psi into the boost signal line.. it you probably blew up that diaphram and killed it.

"The diaphragm is still in good shape."
Which one? the S.S. fuel metering diaphram disc at the top under the fuel line connections or the boost enrichment air pressure diaphram at the bottom?
With all your questions one wonders how do you know that, did you take it apart?

Do you know the overall condition of the ignition, timing, and cold start timing if the hardware is still there and functioning?
