Quick answer: Most disposable problems have one of five causes: the battery is low, the e-liquid is used up, the airflow or sensor is blocked, there's condensation in the mouthpiece, or the device is damaged. Charge it if it has a port, check the liquid window, clear the mouthpiece, and try gentle, steady draws. If it tastes burnt after charging, the liquid is gone. If it gets hot, fires on its own or leaks from the port, stop using it.

Device used up?

If the liquid is gone, it's time for a new one.
