How to create a delay function in a trigger

I have a problem, i need create a function delay in the timeline with a trigger.

I want that my animation play every 3 seconds until the next sym.stop and then play again after 3 seconds.

Ej. I have 3 triggers in the timeline:

sym.stop(1000)

sym.stop(2000)

sym.stop(3000)

My idea is make a delay in all the triggers, like this:

sym.stop(1000)

delay.play (2000)

sym.play

sym.stop(2000)

delay.play (2000)

sym.play

sym.stop(3000)

delay.play (2000)

sym.play

Cause I dont know how to elaborate a function in jquery i pray for your help.

Thx
