I'm getting a heavy fuel smell when starting my S500. Seems to go away when on the road. Can't find any fuel leaks. Any place I should look. How are the injector sealed?

Thanks

please identify exactly where the gas smell is, inside the car cabin? or outside?

Check in the area where the fuel pumps are - A small hole in the high pressure feed line can make a fine mist; so alot of the fuel will get blown away, unless you are not moving, and the plastic shielding eventually fills up and leaks fuel on to the ground.
I found my leak was easy to find in the dark, using one of those high-powered spotlights (engine running).

gurban, many things could be leaking and causing a gas smell at start-up. It's possible the EHA valve has developed a hairline crack that weeps gas ... the valve exterior is wet at a cold start; however, as the engine compartment heats up the leaking gas evaporates so there is no gas smell. Closely examine the EHA valve during a cold start.
