About 3 months ago i bought the T5 kit with the two lenses. After noticing that the cameras flash kills the battery after about 50 shots i decided to buy an external flash flash.
camera works fine with the external flash. The promblem is however when the external flash isnt connected, the popup flash will fire like 5-10 times in rapid concession but wont take a picture. Regardless of the setting.
connect the external flash, no prob. If the camera decides it doesnt need the flash itll take pics with out the external flash.
not sure why its doing this?

If its dark enough to need flash its probably too dark for autofocus to work without helper beam.
That is whats happening; the flash is creating extra light to help focusing. Your external flash probably has a focus assist light as well.
You can control it via custom function:
