David, if the unit has an inducer motor check the flame rod to see if the flame hits it. There is a tray the flame will follow and it gets filled with rust and debris. Check your vent pipe for obstructions. Make sure you do not have a cob web in your burner tubes.
If it does not have the inducer motor, check the pilot assembly. Replace it if necessary.

Furnace shut off after 3 time flame from pilot

Sounds like you may have a weak or bad flame sensor. If the circuit board does not sense a good flame it will not light the burners. Also if your furnace is 5 yrs or newer it should give you a fault on circuit board in the form of a blinking or a code itself.

Coleman furnace fan keeps turning off and on every 10 seconds...

clean your heat/flame sensor with sand paper or steal wool. If the sensor is dirty, it won't detect the heat from the flame and it shuts the gas off. Clean the soot and junk off the sensor and it should work fine. I have to clean mine every year. After spending hundreds of $$ every yr on tech calls..I figured out the problem and in 30 sec I'm up and running again.

Heater lights for about 5 sec and then goes out

One flash on a Ruud furnace indicates failure to ignite. There is a viewing port on the furnace where you can watch the flame. If the ignitor is igniting the burner and then 2 or 3 seconds later, the flame goes out; you most likely have a flame sensor that is dirty or not working. Check to make sure you are getting gas. Check the connections of all wires to the control board. If the sensor is not part of the ignitor, see if you can get to it to clean it with a small wire brush. Make sure there is a good ground connection between the board and furnace frame. If the flame is not traveling all the way to the flame sensor, clean your burners. If the flame burns inside the burners, you may have weak gas pressure. Good Luck.
