Any fuel spill,storage or leak can cause fuel odor inside the car.
If you have knocking from the engine and smoke from the exhaust then you have far more problems than the car just not starting. Sick professional help immediately.
If you've thoroughly washed the car (especially underneath) and the odor remains as crazy as it may sound the next thing to check is the car's battery. Automotive batteries that have a "mechanical" or physical failure (i.e. leaking or are shorted internally and often times begin to smoke) emit a sulphur odor not unlike the smell of a skunk or of a natural gas leak. If the odor is in the engine compartment chances are that's where the problem is.
