    Maybe if you try controlling pin 11, where the pump is connected, and not pin 13, it may help. Also I can't understand your wiring there (but it looks wrong - there are components missing). Please provide a schematic (which you can do using the schematic editor available when you edit your question). Commented Dec 30, 2016 at 12:18
