Can you smell gas under the hood? Did you visually inspect for a gas leak? Also, check the evap system, for leaks.

When I initially troubleshot the problem, I did not smell or detect any leaks under the hood. It only is apparent when the blower is on. Where should I look. Around the fuel injectors? Do you think fuel injector cleaning could help?
As far as the evap system, are you talking about the exhaust?

The evap system routes fumes from the gas tank to engine compartment. Then the fumes are mixed in with the fuel system. Are there any applicable trouble codes? Some of the national brand autostores will check codes for free.
Check the fuel lines, under the vehicle, under the hood. Check fuel rail. Pull the vacuum line off the pressure regulator, any gas in the line? Smell of crankcase oil dipstick, does it smell like gas?
