Just because the gauge doesn't show pressure, doesn't mean there isn't any. It is possible for the low pressure refill valve to stick or plug. If you are familiar with a/c system, install a separate gauge on the low side of a/c system. If you get no reading, STOP. The next safest thing is to take you vehicle to a qualified shop to verify your reading. If you are not that familiar with a/c systems, take your vehicle there first.
