Zero on all cylinders? Got to be something in the head.

Totally toasted head gasket? Cracked head? Warped head? Could be, from driving with a bad water pump. But strange that it would pop up after several successful drives, and zero out all cylinders.

Best guess? Timing error after re-assembly after the water pump change. Interference engine. Bent valves on all chambers=zero compression. Not sure about the economics of repairing a 22 year old car with that kind of damage.

Before I did anything else, I would test the compression gauge on a known good engine. You'd hate to rip an engine apart on the basis of readings from a faulty instrument.

If the compression tests prove accurate, any further examination will require that the head comes off.
