Check to see if the pilot flame has gone out? If so, it is the most common cause of a gas water heater failure that most service professional encounter. You may need to have your thermo coupler assembly replaced, this devise measures the heat from your pilot flame, sending a signal to the main gas control valve letting it know an ignition source is present, permitting your water heater to fire it's main burner.
Your main gas control valve may be bad and needs replacing, This devise cannot be properly tested in the field, and no parts can be replaced, this unit is a factory sealed devise. This is always an expensive repair and given the age, history and condition of your water heater, we may recommend a water heater replacement as a solution to this problem.
PROBLEM B, The main burner won't fire but, pilot is burning.
Possibly be a sensor gone bad and needs replacing, water heaters 2000 and newer now come with heat and or CO sensor.
No gas pressure or not enough pressure to allow the main gas control valve to work properly. The gas inlet connection to the water heater may need to be disassembled and checked for debris, the gas pressure should be tested using a manometer that measures gas pressure, this diagnose should be performed by a specialist.

ELECTRIC WATER HEATERS
PROBLEM A, The water is cold and won't get hot.
Check the breaker marked "WATER HEATER" in the electric panel box, this may have simply tripped and may need resetting however, this may be a cause of other electrical problems going on within your water heater and should be diagnosed and repaired by a professional water heater technician.
Electric heating element(s) may have gone bad and needs replacing. Some water heaters have one, most have two and commercial electric water heaters have as many as twenty.
Thermostats usually upper and lower have gone bad and needs replacing, some water heaters only have one thermostat most have two, upper & lower. Careful "220 volts" these are the most common problems but, keep in mind there are many other reasons why you have no hot water.
