I had the same problem, 1st start the car and let it idle for a bit. Pop the hood and see if the smell is stronger in the engine comp. or in the rear of the car. If it is just in side or towards the back check the fule pump connections as 3050rpm suggested. I had a loose hose coming off my fuel filter under the intake manifold. It would only leak when it was cold, like below 35 deg. An inspection mirror will come in handy here. Hope it helps
