If it sounds like it has no compression then the most common reason would be oil-wash caused by flooding. The extra gas washed the oil from your compression rings. The first thing to do is to check for gas in you lower intake. If you smell it or see it you have to find the source, here are some items to check,
Fuel pressure regulator vacuum line, sometimes the regulator leaks fuel from the vacuum port.
ECT sensor. A bad sensor will cause a warm engine to flood.
Leaky fuel injector (real bad leak).
Once you find the fuel source, correct the problem and dry up the gas in the manifold, then remove your plugs and squirt a small amount of clean oil into each cylinder. (Don�t go crazy here; just a few drops will do ya).
Crank the engine for a few seconds to distribute the fuel. Dry and install the plugs and crank her up. It will smoke until the extra oil burns off.
I have never seen or had a reliable report on any timing chain jumping a tooth. Look at a chain, it just can�t happen. I have seen chains break, sprockets strip and cams break, but never seen a chain that skipped.
