From what I've read, if the car starts up then gets turned off very quickly, or stalls out, it can flood the cylinder with gas, which leads to "cylinder wash". This means there isn't any oil around the cylinder rings, which can lead to no compression. I described a problem as the starter didn't seem to have any "load/resistance" to it, and for the life of me couldn't figure out how there would be no compression. Well, I'd never even heard of this happening before, but in my case...it definately did!
