Rebel T3i built-in flash does not fire
Most Canon DSLRs have a switch in the hot shoe (if you look under the spring plate in the hot shoe one one side there is usually a small white shaft sticking up from underneath the top cover). Sometimes because of spillage etc. this shaft sticks down and the camera thinks that there is an external flash installed so it won't operate the built in flash.
In your case I would be more suspicious of the flash board. Does the flash symbol in the viewfinder light up? When you fire the camera does the symbol go out but the flash doesn't fire? This is a pretty common sign of a bad flash board.
A third possibility would be a broken flash tube. Has the camera been impacted?
Put the camera's mode dial on 'P' and push the flash button on the side of the mount/front cover. Does the flash pop up? Does it fire now? On the P,A,S,M setting the flash fires all the time if it is popped up; if it is one the green rectangle or other setting it only fires if there is not enough light.
Finally reset the menu to factory default in case something is selected that is causing the flash not to fire.
