The boost gauge not reading is a vac leak more than likely. Check all your vac lines and be sure none are leaking. And check the "T" fitting under the S/C snout as they like to crack.

Ok for give my ignorance here but would a leaking LIM also cause a 0 boost reading... Since the boost is measured by the Manifold pressure.....I could be WAY off here.
