So true. If you don't get air out, you won't get air in! Rare problem, but it does happen.

On small engines, this happens frequently as mud daubers like to make homes in the little tail pipes of little engines. On an automobile, it would likely be a prank potato in the tail pipe or a completely plugged converter.

Again, not likely your problem, but it has happened.
