In addition to leaky injectors there is the fuel pressure regulator most (all?) of which work off of engine vacuum. When its diaphragm fails the vacuum is sucking fuel into the intake. This can cause or contribute to a no start when the car has been run and then shut off for a while, and lead to rough, smoky running.
