A fast flashing turn signal, on most any vehicle, is an indicator that a turn signal bulb is going out or has gone out on that side(i.e. front turn signal on passenger side flashing fast, check the rear turn signal bulb on passenger side.) This will cause the light on your dash board to flash fast as well. This is generaly a good time to replace all of the bulbs, turn signal, running lights, and break lights, as they are so cheap. Also check deck light or top break light if applicable for burn outs.
Usually a bad turn signal flasher

Screwed into the head.
Could be a vacuum leak
One of your turning signal or side marker bulbs are burnt out. Whichever side blinks fast - that's the side that has the burnt bulb. I just had the same problem and after I replaced the burnt bulb the fast blinking went back to normal.
Usually mean you have a burnt out bulb. Simply replace it and you should be fine.
If they come on and will not flash, replace the Flasher Relay. If they just don't come on replace the blown out bulb.
