All 3 ports work and it is now obvious that I have a leak somewhere in the line itself (trunk and passenger door latch are on the same line with a small tee in the line ". Pump ain't the problem. Will apply air later today and listen for leak.

The weak spot is the air line that enters the trunk lid. It breaks inside the corrugated tube that the hose passes through on its way to the trunk lid latch. This line is flexed every time the trunk lid is opened, replace the hose if you can with urethane hose not vinyl hose. This weak spot is on the coupe and roadster.
