5,000 ohms isn't good.
Set your meter to read a range of 10-12 ohms which is where the good element should be.

The heating element will burn out within 10-15sec if the HW tank is empty. 
For the gas side some will run the stove inside first to get LP in the line closer to the heater if it hasn't been run in a while. Does the gas side have electronic ignition and can you hear it sparking when trying to light ?
