Normally you test a car with all three plugs out, throttle wide open, coil wire pulled, and with a fully charged battery. I also like to put jumper cables on the battery and attach them to a running car so that there is sufficient charge to maintain RPM across all 3 cylinders. I would also check the compression tester on a known running car to be sure that it is not faulty. Honestly, 0 PSI is pretty hard to achieve unless all three pistons have giant holes in them which is again unlikely.
