    So, my ZX2 developed a vibration in the engine while I was on vacation. It was very weird because it didn't seem to effect engine performance, so I figured I could drive it home and diagnose it there. Well, 45 minutes from home with all the gauges reading normal the engine stops running. I coast it up an off-ramp and try to refire it without luck. Push it into a parking lot and I notice coolant is leaking. I also notice the serpentine belt is just hanging loose. When I touch the water pump pulley, it was loose because the bearings had failed. (No doubt the vibration)
    Well, I've now replaced the water pump (filled it back up) and placed the serpentine belt back on, but it still won't start. Is there some safety cut-off feature the cooling system has to prevent the engine from running? Any ideas of what's wrong?

    Crank but no start I assume ? Check fuel pressure and spark. Look at the wire harness around that area, such as the crank sensor harness, and confirm that none are damaged. (no crank sensor, presumably no spark)

    Crank sensor is at the other end of the engine on the ZX2, Intuit.

    How does it sound when you try to start the car? Does it even try to run?

    Thanks Ck. :)
    Still non-interference I assume....

    It sounds like it's turning over normal, except there's not the familiar interruption from the cylinders as they start to fire. Just a constant hum of everything turning. The speed sounds like it would with a fully charged battery and working starter.

    Run a compression test. It's possible that it ran without sufficient coolant long enough, to take out the headgasket. Otherwise as a basic step, probably good to check timing chain/belt.

    Did the water pump seize up when it died? If it did it might have stopped the timing belt, and if that is the case, from what ik zx2's motors are interferenced so the cams would stop it could damage all of the valves.

    No it didn't seize, the bearing just caused the shaft to wobble. And if it stopped a belt, it would likely be the serpentine belt, not the timing belt.

    And ZX2s are NON-interference. If you go by the Gates catalog listing, it is wrong! No Escort engine has been interference since the 80s.

    Solved it, hopefully

    Congratulations Intuit, you hit the nail on the head! I pulled out one of the spark plugs and it had water on it, which smelled like coolant. The water pump likely failed before the engine allowing the belt to come off and without coolant circulating, the temp gauge stayed normal while the coolant in the engine overheated and burst the gasket. The head is now in the process of being removed.
