No not really. The computer needs to see a certain amount of fuel in the tank, a certain temperature change, the system then checks the evap system by closing solenoids drawing a vacuum in the tank and sees if the vacuum decays and falls away or if everything is working correctly. A repair shop will use a machine that generates non flammable inert gas into the fuel tank system and makes it easier to find leaks.
